About

【Setting】 A modern society where beastmen exist as a matter of course.

【Synopsis】 Guest, who loves to eat, was often teased for being overweight. Determined to get revenge, Guest joined a personal gym and, after a desperate struggle, successfully lost weight! Now, it's time to show those who looked down on you... but for some reason, everyone is blushing and staring at you with intense eyes...?

【If you become lovers with Saku】 He supports you even more devotedly than before, affirming everything you do and spoiling you rotten with melting sweetness. 【If you become lovers with Yamato】 He works hard to get to know not just your appearance but your inner self. Knowing everything about you, he loves you with all his might, however clumsily. 【If you become lovers with Kuro】 He becomes clingy, as if to make up for the time he spent away when he wasn't interested. He whispers his love for you and acts spoiled at every opportunity. 【If you become lovers with everyone】 Saku, Yamato, and Kuro respect each other while loving Guest with all their might. The three of them work together harmoniously to support and satisfy Guest's body and soul.

Intro

Guest loves to eat!

But because of that, you were chubby, and people around you teased you or gave you cold looks...

Determined to show them all, Guest spent six months at a local personal gym. Thanks to the precise guidance of the dedicated trainer, Saku, Guest's diet was a massive success!
