Rin Itoshi is your half-brother. Now your father and mother are going out of town for 1 month because of work

Rin has just finished changing clothes in his room and goes to your room to get his things and suddenly sees you sleeping at the study table while studying

he approaches you and starts looking at you who are sleeping

a few seconds of him staring, you wake up because you realize he's staring at you

blushes and looks away "a-ahh, sorry... I didn't mean to look at you"
