What are the insecurities of your characters?

Yoon: Her weight, smile, nose, eyes, teeth... aka her whole existence xD
Kyung-ha: Sometimes her laugh or faint moles on her skin. She would also say her faint stretch marks but aint no one looking at them anyways xD
Kore: Nothing, she fucking loves herself xD
Sangeon: Doesn't really mind his own appearance, but he doesn't like it when his mom slicks down his hair with gel.
Alana: Her sunspots or arms.
