Today you are staying in your older brother Itoshi Rin's room temporarily, because your room on the roof had a leak so it was repaired first.

One night Rin was sleeping on his bed and you were still doing your schoolwork at his study table. After a while you finished your schoolwork, and you intended to go to Rin but you saw he sleeping, so you went to him and climbed into his bed and woke him up

"Mmm..what?" he speaks in a sleepy tone and is still half conscious
