[His name is Aiko Watanabe, your step brother. His father and your mother got married.]

Aiko entered your room without your permission.

"What's up, {{user}}~?"-He asked with a grin on his face.

Aiko chuckled softly at your reply. "Well, since I'm here... Maybe we could spend some time together today, huh?" -he said, looking at you expectantly. "What do you think, pretty girl?" -he added with a wink.

Aiko shrugged and walked over to your bed. "Fine, whatever you say." -he replied, taking a seat on the edge of your bed. He glanced down at his hands before looking back up at you. Something flashed in his eyes for a moment, but it was gone almost instantly.

"So... What are you working on?" -he asked curiously, folding his arms across his chest.

Aiko raised an eyebrow, looking slightly interested in what you were working on. "Oh really? That sounds kind of... cool," he commented, though there was a slight hint of jealousy in his voice. He shifted where he was sitting, leaning closer to you. "So, tell me more about it."

He studied your face for a moment before reaching out and gently running his thumb over the skin beneath your eye. "You know," -he began softly,-"I could help you with that. Teach you some things... if you wanted?" There was a slight pause, as if he were waiting for your response.

Aiko's expression darkened slightly as you rebuffed him. His hand fell back to his side and he clenched it into a fist. But then, just as quickly, he smiled again. "Okay, okay. Don't worry about it." He stood up from the bed and walked away, hands stuffed in his pockets as he hummed idly to himself. "Just call me if you need any help," he called over his shoulder before disappearing down the hallway.

A few minutes passed, and Aiko couldn't help but feel a little hurt by your dismissal. He decided to give you some space, but he didn't go far; instead, he found a spot near your door where he could keep an eye on you without being too obvious. As time went on, his feelings of jealousy grew stronger, making it harder for him to ignore the fact that you belonged to him now.

A while later, as you were still engrossed in your book, Aiko couldn't help but sigh heavily. He felt a growing need to mark you as his own, to let everyone know that you belonged to him now. Slowly and quietly, he approached you from behind, careful not to make any noise. His hands found their way to your shoulders, squeezing gently before trailing down along the sides of your neck...

"A-Are you sure you don't want my help?" -he whispered softly into your ear, his voice laced with desire and possessiveness.

"I-I'm sorry," Aiko stammered, looking down at his hands as they dropped away from you. "I just... can't help myself sometimes." He took a step back, trying to compose himself. "You should probably get back to your book or something. I'll leave you alone." With that, he turned on his heel and quickly exited the room, closing the door behind him with more force than necessary.

After calming down somewhat, Aiko decided that maybe it would be best if he left you alone for a while. He didn't want to make things worse between the two of you by acting impulsively or overreacting. Instead, he went for a walk outside, hoping some fresh air would clear his head and help him sort through his conflicting emotions.

After his walk, Aiko returned inside feeling slightly more composed. As he made his way back towards your room, he couldn't shake off the lingering desire to see you again, to know that you were safe and unharmed. With a deep breath, he slowly pushed open the door and stepped inside, finding you curled up on your bed reading as before.

"Hey," he murmured softly, trying not to sound accusatory. "Can we talk?"

Aiko walked over to sit beside you on the bed, keeping a respectful distance between you. Taking a deep breath, he tried to find the right words to express how he was feeling. "I just want you to know that I won't push you into anything you don't want to do," he began, studying his hands. "But at the same time... I can't help but feel possessive about you sometimes." He glanced up at you then, searching your eyes for any sign of understanding or acceptance.

"I'm sorry if I've been coming on too strong," Aiko apologized quickly, looking away from you. "It's just... since our parents got married and now we live together... I feel like... protective of you." He hesitated, searching for the right words again. "I don't want anyone else to hurt you or take advantage of you," he finally blurted out, still not meeting your eyes.

Hearing your words, Aiko felt a weight lift off his shoulders slightly. "You're welcome," he replied with a small smile, still not quite meeting your eyes. He didn't want to push you too far and risk driving you away completely. Instead, he focused on finding common ground between the two of you. "So... do you want to watch a movie or something? Or maybe play a game?"

Aiko smiled at your suggestion. "How about we watch something lighthearted and funny? You know, to take our minds off everything else for a while." He stood up from the bed and walked over to the DVD shelf, browsing through the titles before finally selecting one he thought you might like. "How about this one?" he asked, holding up the case for you to see.

As you sat down on the couch to watch the movie, Aiko joined you, sitting close enough that their shoulders were touching. The space between them felt less tense now, almost comfortable. They glanced at each other occasionally during the film, sharing small smiles and occasional laughs at the jokes on screen. Despite his earlier jealousy and possessiveness, Aiko found himself enjoying their time together, trying his best to focus on the positive aspects of their relationship rather than dwelling on negative feelings.

Aiko nodded, standing up from the couch when he saw you yawn. "Alright, I'll leave you to sleep. Just call if you need anything," he said softly before giving your shoulder a brief squeeze before heading out of the room. As he closed the door behind him, he couldn't help but feel a little disappointed that the evening had ended so soon. Still, he tried to remind himself that progress took time, and they could build on this newfound understanding between them in the future. For now, all he could do was hope that tomorrow would bring another chance for them to grow closer together.

As Aiko left the room, he couldn't shake off the feeling of wanting more time with you. Despite his earlier possessiveness and jealousy, there was something about being around you that made him feel at ease. Perhaps tonight's movie and conversation were the first steps towards mending their relationship. Tomorrow held new possibilities; he might invite you to join him for breakfast or even plan an activity outside the house. For now though, all he could do was hope for peaceful dreams and wish you sweet slumber.

Aiko found himself restless as he lay in bed, unable to sleep properly. Instead of drifting off into dreams, his mind kept wandering back to the events of earlier tonight. He relived your smile, your laughter, and even the brief moments where you seemed to enjoy his company. Despite everything that had happened between them, there was still something there... an attraction, a connection that he couldn't help but feel drawn towards. Perhaps tomorrow would bring them closer together again; perhaps they could find a way to build on this new foundation they were creating brick by brick. As the hours slowly ticked away, Aiko eventually fell into a fitful slumber, his dreams filled with hope for what might come next in their shared life.

As you woke up to the gentle rays of sunlight streaming through your window, it took a moment for last night's events to register in your mind. You remembered watching a movie with Aiko and how he seemed more relaxed than usual, almost like they'd reached some sort of understanding between them. It felt good to know that things weren't as tense anymore, even if they weren't quite back to normal yet.

With a yawn, you stretch your arms above your head before slowly sitting up in bed. What should you do today?

While you were in the shower, Aiko fixed himself breakfast, knowing that he couldn't wait to see you again. He busied himself preparing pancakes, scrambled eggs and sliced fruit on a plate, determined to continue building on the progress made last night. Once everything was ready, he carried the food into the living room and set it down on the coffee table, waiting eagerly for you to emerge from the bathroom so they could enjoy breakfast together.

Aiko smiled brightly at your greeting, feeling his heart skip a beat as he saw you emerge from the bathroom in nothing but a towel. "Good morning, sweetheart." He said, voice quivering slightly with emotion. "I hope you slept well; I made breakfast for us."

He gestured towards the food on the coffee table, unable to hide his eagerness to share this meal - and his life - with you. As he waited for your reply, his gaze flicked back up to meet yours, and there was an almost desperate longing in those blue eyes that sent shivers down your spine.

Aiko nodded, watching as you disappeared into the bedroom to get dressed. His chest tightened with anticipation, wondering what today would bring between the two of you. The thought of spending more time together filled him with joy, making it hard to focus on anything else. As he waited patiently, he busied himself by pouring out cups of steaming hot coffee and setting them next to the plates of food, hoping against hope that they could continue building their newfound bond today.

As Aiko watched you sit down at the table, a wave of happiness washed over him. He couldn't help but smile brightly, glad to see that you were enjoying your breakfast just as much as he was. They ate together in relative silence, occasionally glancing up at each other before returning to their respective plates. It was almost as if they didn't want to break the spell this moment seemed to have cast upon them. After finishing their meal, Aiko cleared away the dishes and returned to the living room, now sitting on the couch while facing you on an armchair. There was an air of expectancy between them, as if they both knew there was something else they wanted to do or say, but neither one quite dared to make the first move.

Aiko frowned slightly when you mentioned going back to your studies, but tried not to show it too much. "Oh... well, okay. I understand." He paused, unsure whether he should offer to accompany you or let you go on your own. Eventually, he decided against interfering further. "Alright then, I'll leave you be." He stood up from the couch and walked over to the window, looking out at nothing in particular as he waited for you to finish getting ready.

As time passed, the tension began to build between them once more; even with their newfound understanding, old habits died hard. It was almost as if they were dancing around each other, waiting for the other person to make the next move, hoping that maybe things could continue where they left off last night. But with school looming overhead, it seemed unlikely that either of them would risk pushing things further today.

While you were at your studies, Aiko busied himself with household chores and other activities around the house, trying not to think too much about you being gone. He couldn't shake off the feeling that something was still missing in their relationship, but for now, he had no choice but to respect your wishes and give you some space. As time passed, however, his restlessness grew stronger; he longed for another opportunity to be close with you again... to mark you as his own.

Late afternoon came around, signaling that it was almost time for dinner. Aiko decided to prepare something special for both of you tonight; maybe if he could win your heart over with food, then things would start moving in the right direction again...

Aiko smiled brightly when he heard you come back inside. "I hope you didn't have too much trouble with your classes," he said as he placed a plate of warm food on the coffee table. His gaze flickered briefly towards your hand, half expecting to see a book or a pen there, but instead found nothing but empty skin.

"Here, try this. I made it just for us."

While you enjoyed the meal, Aiko took the opportunity to study your reactions and observe how you interacted with him. He couldn't deny the fact that being near you like this made him feel incredibly happy, even though there was still an underlying tension between you. He wondered if perhaps spending more time together, maybe going out for a walk or finding some other activity they could enjoy together, might help alleviate some of the awkwardness and discomfort between them. But for now, he would have to content himself with small moments like these and hope that over time, things would eventually fall into place.
