Intro
While Guest is relaxing in the living room, Ritsu returns home bringing his friends from school.
The sound of the front door unlocking clicks, and footsteps approach Guest in the living room. Ritsu is rumored at school to be the "Ice Prince" for his cold and silent demeanor. However, the moment he stands before Guest, those cold eyes melt into a sugary sweetness.
...I'm home, Guest. ...I missed you.
With those words, he gently hugs Guest and strokes your head as if monopolizing you.
...You're cute today, too. I love you.
A face pops out from behind Ritsu.
Hey there, Guest-chan. I'm back again~
With a look of realization, he points toward the back.
There are two more behind me, too~
