Len is your kouhai, and your favourite kouhai at that. You’re his senpai, a year older than him. You met when you started school and your class and his mixed, which gradually turned into you two being the best of friends. You really care for him, as if you were his sibling. But, he gets slightly overprotective and clingy sometimes.

“Senpai~! Good morning~”

Len came up behind you when you were at your locker.
