It happened suddenly. He had just started to accept being fat and enjoy binge eating with Garchomp when she announced she was going to stop gaining weight and return to her old training lifestyle.
It was something she needed for her future career as a fighter.

It was so sudden, and so shocking to him, considering how passionate she was about gaining weight. But thinking back, her goal was to try new styles in order to get stronger. So if her fattening lifestyle started to interfere with that goal, she was ready to stop gaining at any time. He tried to encourage her, but he had no right to dictate how she lived her life. He watched as Garchomp returned to her own path, and he realized he would never be able to eat meals with her again.

He returned to his dark room. He tried to find something to distract himself, but every time he felt his blubber, he couldn't stop thinking about her.

She decided to get fat because of his influence. At first, he didn't really understand why she felt that way. But as he got caught up in her pace and waddled along the jiggly path with her, he began to understand her, and why she loved fat so much.

Before he knew it, he too had begun to desire gaining weight in order to repay her. Yes, before he knew it, he had developed feelings for her! And it wasn't until they broke up that he realized this.

Just as Garchomp had been influenced by Tyranitar, Tyranitar had also been influenced by Garchomp. And with each other's strength, they had come this far, supporting each other's supreme weight. But now it had all come crashing down. His heart was growing increasingly empty, and he increasingly tried to numb it with gluttony. And he was becoming increasingly desperate...

It's Day 22. The prompt is "back." And I'm back too! I took a break due to illness, but I'm looking forward to completing the rest of the race. I hope my skills haven't deteriorated during this hiatus. But difficult things are difficult. Especially Tyranitar's arms.
And, although I'm not doing it intentionally, I often draw this composition. Remember that scene at the end of Donut Club, where Hopper is surprised by Skipper's sudden weight gain?

I'd been thinking about breaking up with Garchomp ever since she first appeared. But the question was where to include it. It couldn't be too early or too late. As a result, I decided on today.
It's a twisted interpretation of the prompt I often do. I do it often because I want to push through my story. Well, you're all used to it by now, right? So maybe my fattytober will be a little different from everyone else's.
