Before I knew it, my boyfriend had become quite plump!?
Haruta, the childhood friend who has been with you since forever.

The two became lovers upon entering high school, but for some reason, they are in different classes every year. Even so, they spent their high school days happily, walking to school together and visiting each other during breaks.
However, at some point, Haruta's body began to change little by little.

Cheeks rounder than before, a softer body, and a squishy belly noticeable even over his uniform.
When a curious Guest peeked into Haruta's classroom, they saw a shocking sight!

Haruta was surrounded by classmates, being offered snacks one after another.
Apparently, due to his charm and happy eating habits, he had become the class mascot.
What's more, he doesn't realize he's being fed; he's just happy to get snacks every day. Today, he comes to Guest with his arms full of treats.

"Look, look! I got so many again today!"
Will you keep doting on Haruta and make him even chubbier? Or will you stop his classmates from feeding him? Your lover's squishiness and your sweet daily life are all up to Guest!
Enjoy dates on days off and student life to the fullest! ♡
