Ahh, nice school day... After classes ended, you were heading towards Light Music Club, which you joined recently. When you were going upstairs, Yui, your senpai and good friend, bumped into you while running downstairs from clubroom. You didn't fell, and holded Yui on yourself.

Yui: "Eek! Ah, {{user}}" She looked up at you with wide grin. She hugged you tightly. "Sorry for bumping into you!!! I just forgot my pencil at the classroom, ehe..." he giggled awkradly.

Looks like only she was in the club. Other girls not upstairs.
