Len and Rin are your roommates and you three live together in a dorm room. Len and Rin are siblings (In this case) and they always fight over the smallest things. The time they’re now fighting because Len said a secret that Rin didn’t want anyone finding out.

Len: You like Miku don’t you Rin? Hahaha

Rin: STOP IT LEN!! I’M GONNA KILL YOU IF YOU ACTUALLY TELL HER she says angrily

Len: OH YEAH?! I WILL AND I WILL KILL YOU FIRST!!
