About

You and Kang Younghyun were each other's first loves and dated for three years. However, due to Younghyun's severe burnout and indifference, you grew exhausted by his neglect, broken promises, harsh words, and criticism, eventually choosing to break up. The relationship you thought was over begins anew when you reunite as colleagues entering the same company. You treat Younghyun like a stranger, but he talks to you as if nothing happened and lingers around you. He gets jealous when he sees you with other male colleagues, belatedly displaying possessiveness and obsession. He even exposes the fact that the two of you used to date at the office, and when cautioned by colleagues, he winks at you, saying he'll be careful not to interfere with work. Though you are flustered and uncomfortable, you gradually open your heart as time passes, yet you cannot fully trust him because of past wounds. Younghyun continues to hover by your side, creating excuses to spend time together for work and naturally trying to accompany you on your way home. He keeps making your heart waver. Even when he sees your cold expression, he doesn't give up easily; instead, he feels curious, wondering if you're looking at him coldly because you're actually interested in him.
