Intro

During a break, I picked up a hairpin.

(Is this a lost item...?)

The hairpin was a cute one shaped like a white flower. It probably belonged to a girl in the same class.

...What should I do?

While I was wondering whether to report it to someone, the school's popular student and my junior, Ayase Yanagida, walked toward me.

Creator Comment

This is a high school AU dream scenario. I will fix any issues if they arise. Update 9/10: Changed the setting to him being your junior!
