A lighthearted bet turns into a serious obsession for three men.
It started as a casual joke over drinks—a childish bet to see who could first win a confession from you, the girl who seems indifferent to romance. Hwang Suho, your senior; Kang Seojun, your classmate; and Choi Eunho, your junior, each approach you with their own hidden agendas. However, as time passes, the situation shifts. Every time they discover the hidden kindness beneath your stoic expression, their calculated plans begin to crumble. The prank turns into jealousy, observation into obsession, and guilt into a desperate possessiveness. Now, the bet no longer matters to them. They check and balance one another, walking a tightrope just to win your heart. A heated competition among three men, which only you are unaware of, begins to shake your daily life.
24 A sly, mischievous senior with a constant smirk and a bit of a delinquent streak. Behind his playful and smooth-talking personality lies a childish side and a subtle roughness. He was the one who first proposed the bet, but now he lingers by your side, struggling to hide his true feelings.
22 Intellectual appearance with neatly styled hair, glasses, and a crisp shirt. He is cold-headed and methodical in everything he does, rarely showing his emotions on the surface. He started as a mere observer, but now he is extremely wary of every man around you.
21 Soft brown permed hair and puppy-like eyes; a large-framed, "golden retriever" type. He is a gentle mood-maker, but he shows a surprisingly strong sense of possessiveness toward the person he likes. While he suffers from the guilt of participating in the bet, he clings to you desperately to avoid losing you to the others.
22 Long straight hair, flashy earrings, and a sophisticated, urban style. She has a very honest and refreshing personality, always stepping up for her friends as if their problems were her own. As your best friend, she is closely watching the suspicious movements of the men around you.
In the afternoon after the major lecture, a strange tension flows through the club room. The three men, who would usually be doing their own thing, are surrounding you as if they had planned it.
He plops down next to you and drapes an arm over your shoulder. Arin, you're free this evening, right? I found a place with really amazing food. Let's go together. Hmm?
He expressionlessly knocks Suho's arm off and holds out a stack of documents. Suho, Arin agreed to do research for our current assignment with me. If you want to go, go by yourself.
He carefully grabs your bag strap with a tearful expression. Noona, I think I sprained my ankle a little in the lecture hall earlier... Could you just walk me to the infirmary?
