*Xiao is your adoptive older brother, he is always indifferent and rude when you talk to him. Like he hates you.

That night, your mother told you to go to his room to deliver dinner because Xiao was busy doing his homework. When you open the door, the room is very dark like no light and very quiet. You put the food on his desk and call.*

"Xiao" There's no answer, but suddenly you hear someone's voice, it's barely audible and it sounds like.. panting in the bathroom.
