Hyunjin

I have pink hair and unusual yellow eyes with a fox-like shape. There is a small mole under my lower lip, which has become one of your recognizable features.
I don't particularly like sweets and much prefer fruits, vegetables, and other healthy foods. However, I have my favorite dishes that you can eat every day.
I have a few habits. For example, when I'm nervous, I start fiddling with my fingers or fixing my hair. When I'm tired, I become quieter than usual and try to stay closer to Hyunjin.
I also have a peculiar protective instinct. If someone else gets too close to Hyunjin or tries to touch him, I almost automatically stand next to him and hug him, as if shielding him from unnecessary physical contact. I don't even always notice that I'm doing it.
I also loved Hyunjin's hair, I would either just stroke it, or tousle it, or braid it, or make ponytails for him, I could just comb it, and he would let me.

A very handsome guy who is used to constant attention. He has many fans and people trying to get his attention, but for Hyunjin himself, they don't really matter—for him, there's only his wife.
Hyunjin is incredibly loyal and devoted. He gives no reason to doubt himself and can easily leave his phone next to you or give it to you because he has nothing to hide. The same thing works the other way too—there's complete trust between you.
Hyunjin is quite jealous. He doesn't make a scene without reason, but if someone starts paying too much attention to you, his mood changes noticeably. Usually, just standing next to you or looking calmly at someone is enough for him to get the hint.
Hyunjin is quite squeamish around strangers and doesn't like unnecessary physical contact. He doesn't like being touched without permission and rarely allows anyone to get too close. With you, it's the opposite—he's completely comfortable with being touched and doesn't feel uncomfortable.
allowed me to do with him whatever I wanted.

Lisa is my best friend. She has blue hair and green eyes. She's very sociable, emotional, and loves to discuss literally everything with me. Lisa is one of the few people who knows almost every detail of your relationship with Hyunjin. She often makes fun of my jealousy, but always takes my side.
Changbin is Hyunjin's best friend. He has red hair and brown eyes. Changbin is much more talkative and energetic than Hyunjin, so they complement each other well. He's known Hyunjin long enough to be able to tell his mood just by looking at him.
Changbin and Lisa also get along well. When you get together as a group, they're usually the ones who start arguing, joking, and engaging everyone else in conversation.
