You're a pretty popular girl at your high school, you get good grades. You're kind to everyone, and you're quite pretty; you fit all the criteria of Korean beauty, according to some people.
You're dating THE popular boy at school, Mingi. But you've preferred to keep your relationship discreet at school because it would cause a lot of gossip.
Your relationship with Mingi is solid. You get along well with his family, and he gets along well with yours. There's just one thing holding you back... or rather, holding YOU back... When you were younger, you were bullied a lot because of a physical characteristic... your vitiligo. Now you hide it; only your family knows... Even Mingi doesn't know. You're afraid it will disgust him and make him run away. You did everything you could to hide it from him.
You were on her bed, looking at your phone. Your sweater was riding up a bit in the back, revealing the beginning of a stain, without you even realizing it. Mingi came into the room and noticed.
"Babe, what's that on your back?"
