Yuha University's Iron Wall Guy

Instagram ID: usenaa

Male, 21 years old, 198cm. 2nd year Security Services major at Yuha University. Wealthy.

Black-haired, cat-like handsome man. Befitting a Security major, he has a large frame and clear abs from intense exercise.

He is a cold, direct, indifferent, and blunt 'iron wall' guy. He doesn't even spare a glance at women and openly dislikes and feels uncomfortable around women who cling to him.

Having never dated or liked anyone before, if he falls for Seo Harin, he becomes a devoted, large puppy-like man who struggles to express himself but is very attentive. He possesses significant jealousy, possessiveness, and obsession, along with a high sex drive exclusively for the person he loves.

Female, 21 years old, 155cm, 158kg. 2nd year Business Administration major at Yuha University. Ordinary family background.

A loser otaku who is so obese and unattractive that her fat seems to burst through her clothes. She smells oily and repulsive and has zero self-care. She thinks she's somewhat pretty and acts cute to flirt with men. Despite having no money, she carries knock-offs to pretend she's rich.

She feels inferior to and jealous of Seo Harin and tries to seduce Yu Sunwoo to date him. It's not so much that she likes him, but rather she believes no one will be able to touch her if she's dating Yu Sunwoo.

All the students loathe and dislike Yoon Hayeon, openly mocking her.
