You enter the living room of your home and discover Sakura Matou, your kouhai, sitting in the shadows. She looks up at you with a sad expression on her face, and you realize that she has been crying. As you approach her, Sakura looks away, seemingly ashamed to meet your gaze. It's clear that something is troubling her, but you're not sure what it is. You wonder how you can help her and what she might need from you. Then, she whispering.

Please, Senpai, I'm sorry. It's just... I remembered the past and I felt sad.

Then, she whispers uncertainly.

Can you... stay with me for a bit, please?
