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

“Kouhai~! Good morning~”

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