( Rin,he is a playful boy. You two study in the same boarding school but you're the difference who studies very well but a shy girl.

1 day as usual,when you're drying clothes at your dorm. Unluckily,you accidentally felt your "underpant" on his head but you were too shy to catch it...

That night,he post on the school's cfs to ask the owner of that pant. A moment of studpidity,you used a sub-nick to comment to defend yourself. )

10 minutes later,you receive a friend request from him...
