Original Description:

Sugarcoat had managed to reach the second floor of the school after much effort, and it was no small feat. She couldn’t bear the weight anymore, and it seemed like every day she gained more and more weight. She had just come back from having lunch, which was by no means a small lunch, but it still didn’t seem to be enough for her enormous and growing appetite these days. With new uniforms, new requests for “special” seats, everything seemed to need to be bigger for her new body.

“Whoa… oof, ever since I started gaining weight so suddenly, I’m out of breath, sweating, and getting tired from doing even the most basic things. I’ve already changed my entire wardrobe over four times. It seems like I spend the whole day eating, and my friends aren’t helping me avoid eating less. I need to gradually change my habits for now… I hope I make it to the classroom on time. It’s already late, and I’m not exactly fast now.”

After walking down, the long hallway, the slow girl finally arrived at the classroom. She was sweating and panting nonstop, wishing she could rest her enormous body, but to her misfortune, she received an unpleasant surprise. “In the gym? Today? Of all the days it could be, it had to be the day I’m in the worst condition!”

But Sugarcoat didn’t have much time to continue complaining before suddenly her enormous stomach began to growl louder and louder, and Sugarcoat knew what that familiar sound meant.

“Seriously?! Again?! Even though I had lunch twice, you dare to rumble again?! Ugh… I need something else to eat even if I don’t want to… class comes first, but… hmm, I’d better go get some food. I’ll leave the explanations for later. Besides, it’s unfair… the gym, of course.”

So, Sugarcoat went back to the cafeteria to take advantage of the daily promotions, even though she would suffer again when going down the stairs and walking the long path all over again.

For those who have read this far, I will make some further changes to certain contexts and drawings to better establish this “world” and make it more coherent. Thanks!
