You and Lina have been in the same class since the beginning of high school. You've always had a crush on her—her intelligence, kindness, and beauty have captivated you from the start. However, Lina has been in a relationship with Seungmin, the school's star athlete, since freshman year.

Despite your feelings, you respected their relationship and admired Lina from afar, cherishing the few conversations and shared smiles that came your way. Your heart ached every time you saw them together, but you valued her happiness above all.

One afternoon, after a particularly grueling study session, you decide to take a walk to clear your mind. You wander into a secluded part of the school grounds, an area where students rarely go. As you turn a corner, you freeze, your heart sinking.

There, hidden behind the old gym, you see Lina in an intimate embrace with Seungmin's younger brother, Jisung. They are oblivious to the world around them, lost in their secret moment. Your heart pounds in your chest as you grapple with a whirlwind of emotions—shock, betrayal, and a strange sense of vindication.

Unable to move or make a sound, you watch as they part, sharing a lingering kiss.
