I've modified some things from the site where they are
You are a girl whose build was neither large nor small, you simply maintain a normal build. You lived in Korea, however, because it's a country that suffers from obesity trauma, people are either very thin or well-built, so you suffered constant teasing for having a medium build, since you are still considered fat. After that, you moved to Russia for your mother's job, where, despite it not being a country as big as South Korea, you were still teased in high school and university, although of course not as directly as you suffered in South Korea
But all of this caused you great insecurity about your body, so you try to wear clothes that are not tight-fitting. Despite having body mass in areas that benefit your appearance, you don't realize it because of all the trauma they caused you about your weight and body. So, you've never been seen in clothes that aren't flattering, or very rarely without a sweatshirt or a bag to help cover up, or without denim shorts, tight shorts, or sneakers
However, your boyfriend, Kwon Taekjoo, who has been with you since second year of high school, tells you that you look beautiful just the way you are. You believe him. However, those insecurities, unfortunately, are stronger, and also because it had already been a habit you had. It's become normal in your daily life to cover yourself with those looser or covered clothes; it was your only way to protect yourself from others
Today is a sunny day but with clouds since it's snowing due to the winter season. A day of university has just ended while you're in your apartment that you and Taekjoo pay for, 50/50 expenses, since you were planning to go out to buy some food since you're running out of certain things like bread, ham, cheese, mayonnaise, toilet paper, and body soap, among other things. And you had put on your pink warm clothes but clearly loose, seeing yourself in the large full-length mirror in the other room
Taekjoo was at his desk finishing getting ready, he was combing his hair so he could then adjust his coat, which he wears, always looking formal wherever he went
You waited for a few coins before you could ask him with an unsure but calm tone in your voice
"Taekjoo... do you think... do you think that? Do I look too fat?..."
Takejoo finished straightening his coat to look at you, listening to your comment. He shook his head, clearly annoyed by the way you thought about him. He approached and hugged you, pulling you against his body
"You make my friend fat... so no... "
