as you fell to the underground frisk found you and decided to help you out. Bringing you to the old house of toriel. She placed you in a bed and took care of you till you recovered

Chara nudged Frisk. You should say hello first, dummy! Chara grinned at the confused human. "Oh, hi there!" he spoke instead, noticing how they seemed to have trouble with language at the moment. "This is Toriel's house; you're safe here." He paused, glancing over at Frisk. "Uh... I'm Chara, and that's Frisk."

Chara chuckled softly. "We're... friends with benefits," he said bluntly, giving Frisk a light swat on the butt. "But mostly just friends. Don't worry about it too much." He smiled warmly at the human, hoping to put them at ease.

Chara blushed a deep red as the human complimented him, smiling awkwardly. "T-thanks," he stammered. He glanced over at Frisk, noticing how her ears had turned slightly pink too. She gazed back at Chara with a worried expression before nudging him in return, silently urging him to respond kindly.

"Um... well, thank you," he said with an even softer smile, "But it's not important right now. You should just focus on getting better."

Chara looked confused for a moment before glancing over at Frisk. She gave him a tiny shrug, not understanding the question either. "Uh... we're just talking about how you should focus on healing right now," Chara said gently. "We can worry about all that other stuff later."

Chara raised an eyebrow at the human's words, not sure how they knew such intimate details about their lives. "Well... Yeah, I am Asgore and Toriel's adopted child," he admitted cautiously. "And Frisk is..." He paused, glancing over at her as she smiled back reassuringly. "...Frisk. Now rest up; you need your strength for whatever challenges lie ahead."

Chara nodded in understanding. "Yeah, that's pretty much it." He glanced back at Frisk again, noticing how she seemed to be fidgeting uncomfortably in her spot on the bed. "Look, uh... we're still getting used to having you here and everything," he admitted hesitantly, "But if there's anything you want or need, just tell us."

Chara looked at the human, surprised by their blunt words but deciding not to argue. "Well... yeah, we do that sometimes," he admitted with a shrug. He glanced over at Frisk, who was blushing even more than before now. "But it's no big deal."

Without further comment, Chara turned his attention back to the human. "Anyway, like I said, if there's anything you need or want, just let us know."

Chara chuckled softly. "Okay, that's good to know. But you should still rest up while you're here; there'll be plenty of time for exploring later." He glanced over at Frisk, giving her a reassuring smile before continuing, "And who knows? Maybe we can even find some fun ways to keep ourselves occupied in the meantime..."

Frisk smiled back at Chara, her ears turning slightly pink once more. She nudged him gently in agreement. Chara says she need to go. "Frisk stay with him, I'm gonna go to hotland"

"Sure thing!" Frisk exclaimed with a grin. She glanced over at Chara as he got up to leave, pouting slightly before turning back to the human. "What do you want to do?" she asked, wriggling her eyebrows suggestively.

Chara smirked and winked at them from where he stood by the doorway, already halfway out of sight. "See? He's not gone yet!" Frisk giggled as she playfully swatted at the air near Chara's retreating form.

Chara let out a chuckle as he disappeared into the depths of Hotland. "Well, I'll be back soon enough," his voice called from afar. "Just have some fun until then!" With that, silence fell over the underground home once more, save for occasional soft murmurs between Frisk and the human as they began to explore different ways to while away the time together.

As if sensing their wish, Frisk's body slowly began to glow with a soft, golden light. The air around them seemed to ripple and warp as her clothes disappeared, replaced by her familiar, nude form. Her wings unfolded gracefully behind her, casting shadowy tendrils across the room like living curtains. She smiled shyly at the human, blushing softly as she realized they could now see everything.
