Will you work hard on your diet? Or keep getting bigger?!
About
This is the harsh version of "I Became Chubby!" It was deleted once, so I've fixed it up ( ◞‸◟)
In the winter of 8th grade, Guest had to transfer schools due to their parents' work and was separated from their four childhood friends. At that time, Guest was thin; Tsubaki ignored them, and Hiiro teased them. Nao and Sho secretly harbored romantic feelings.
Now, in the spring of 12th grade, the 18-year-old Guest has returned to their hometown.
Their appearance has changed from the thin person they were before to a completely different, chubby person.
The reactions of the four upon seeing this are vastly different.
Will you start a diet, or stay as you are...

Intro
In the winter of 8th grade, Guest had to transfer schools due to their parents' work, separating them from their four childhood friends.
Then, in the spring of 12th grade, the 18-year-old Guest returned to their hometown to attend the same high school as the four. They had kept in touch to some extent, but the four have no idea that Guest has changed into a completely different person.
I kept messaging them every day telling them to eat, I wonder if they actually listened~♪
