Until that happened, it was just a normal day. After dinner in the spacious dining room, he waddles to the bedroom, stroking his belly, which is full of bowls of rice and smoothies. If he goes straight through, his wide rear gets stuck on the doorframe, so he turns sideways to go through. Even then, his butt and gut rub against the frame at the same time, but that's been the case for a while, so it's not a big deal now.

He turns sideways and enters the bedroom with his right foot. He brings his butt cheeks closer to the frame to make space for his belly to pass through. He tries to slide his belly into the room...but he can't. Maybe the angle was wrong. He tries to push his belly back against the frame...but he can't. He takes a breath, holds his jiggly belly in his hands and tries to escape...but he can't. He can't do anything... Maybe he's stuck?

No, that's not funny! He grabs the door frame with both hands and rocks his body back and forth to try to escape. With each attempt, the room shook, the ceiling light swung like a pendulum, the books fell, the bottles wobbled and sounded like they were about to fall. The calendar, which was firmly pinned down with thumb tacks and which he had almost forgotten about, was also swaying from side to side. The door frame made a destructive and ominous sound. He could have solved the problem by destroying the door, but poor vandalism would destroy the foundations of the entire building and, in the worst case, the building would collapse... so he didn't want to do that. He just hoped he could escape this situation without destroying anything. And his wish came true.

He collapsed forward into the bedroom, causing a big earthquake. He was stunned for a while, but quickly came to his senses and looked around the whole room. Small items were scattered around... but nothing was broken, including the door frame. Thank goodness, he was relieved, and he wanted something sweet. He was thinking back on the series of events while drinking the smoothie he had kept under his bed. He had gained a lot of weight. If he continued to gain weight... would this become his daily life? Or would he really be trapped in the room? To avoid that, he needs to lose weight... or...

Putting a smoothie in his mouth, he takes out his phone and opens the browser. He checks out door renovation companies one by one. Luckily, they're all cheap, and the work itself seems to be completed quickly. He calls without hesitation, and in a deep, slightly out of breath voice, he completes the renovation procedures. When he's done, he slaps his lardy belly while staring at the tall, but not very wide, doorframe for a large kaiju pokemon. Was this a good choice? Will it encourage further gains...? Then he then looks at the calendar with no presence, which reads October 12. Come to think of it, what date is it today...
=====
It's Day 12. Today, the art isn't that elaborate either. There's not much he can do when he's solo...

A note about him: his story does not take place from October 1st to 31st of a certain year. In fact, several years pass between parts 1 and 31. And because he checks the dates and schedules on his phone, he often forgets about the calendar on the wall, so the dates on the calendar are often not correct.
