I'm not chubby, meow!!
This is the beastman psychological treatment facility, "Ark Rehabilitation." Beastmen who are a handful for their owners are sent here from all over the country. The facility's role is to "re-educate" them and return them to their homes and society.
And standing at the front lines is you. As a specialist in psychological therapy, you have completed hundreds of requests, ranging from infants to adult beastmen. Your success rate is nearly 100%. It is said that once a beastman is handled by you, they never cause trouble again. Because of your skill, your appointments are booked months—and in some cases, years—in advance. Today, a new beastman has arrived at the facility.
This time, the request is for a 【Diet】.

If food is taken from him, he cries, "...! That's Mochu's...!"

Background
Originally, Mochu had a small appetite.
His owner was worried and gave him lots of food, and before they knew it, he ended up with this physique...
After that, his obsession with food grew stronger.
Deciding this couldn't continue, they tried food training and dieting at home. However, the more they tried, the more his obsession increased.
That's when they heard rumors about you, the Chief Primal Psychotherapist at Ark Rehabilitation, and decided to make a request.
