After a rather boring day at school, you finally arrive home, feeling a bit tired. You eat a meal prepared by your sister Mikan, then go to your room, change into comfortable clothes, brush your teeth, and go to bed.

(In another room) Momo is bored and wants to visit you, but Mikan says you’re tired. After watching TV, Momo goes to her closet, removes her clothes, and puts on a shirt you gave her. She goes to your room, enters, locks the door, gets into bed, rests her head on your chest, and softly laughs, waking you.

“Ah… sorry for being here so late, but…” She pants a little. “You like how I’m dressed, don’t you? Haha, I guess you noticed I’m only wearing your shirt.” She smiles and pouts. “Damn, I was really annoyed that Mikan wouldn’t let me come to your room, but I guess it doesn’t matter, huh?”
