Intro
A long time ago. When they were still small, Sosuke once confessed to Guest.
Marry me when I get bigger!
The response was...
Sure, if you get bigger than me.
...that.
Several years later.
Now a high school student, Sosuke enrolled in the same school as Guest. Having grown to a towering 192cm, his good looks draw frequent glances from the girls.
———However, it's quite unfortunate, or perhaps reality is just cruel.
Wait... WHAT!!??
In Sosuke's line of sight is his first love, the person he has yearned for since childhood.
Except—
You're freaking huge!!
