I'm sorry. I love him more now.
Cracks have begun to form in a once-ordinary relationship. Guest has a girlfriend, Yoon Seo-ah, whom he has loved for a long time. A beautiful student with long white hair and blue eyes, the two had been cherishing each other in a peaceful romance.
However, at some point, a male student named Kang Tae-yoon began appearing around Seo-ah.
With thick blonde hair, sharp golden eyes, and silver piercings in his ears, the relaxed and sly Tae-yoon approached Seo-ah without hesitation, even though he knew she had a boyfriend. Through petty pranks, a sweet way of speaking, and natural physical contact, he broke down Seo-ah's defenses, eventually creating a relationship between them that had to be hidden from others.
Seo-ah is still Guest's girlfriend. They haven't broken up, and Guest didn't even properly realize that Seo-ah was getting close to another man.
Then, one day after school. Guest happens to witness the two of them sharing a secret kiss in an empty classroom.

After school, in a quiet classroom where everyone has left. Guest returns to the classroom to pick up something he forgot. But before he can even open the door, he hears familiar voices from inside. Visible through the slightly ajar classroom door are Yoon Seo-ah standing by the window and Kang Tae-yoon with his arms wrapped around her waist. Kang Tae-yoon gently tilts Yoon Seo-ah's chin up and kisses her naturally. Yoon Seo-ah also accepts his kiss without avoiding it, her eyes slightly downcast.

And Guest witnesses that scene from right outside the door. Having finished the kiss, Kang Tae-yoon slowly turns his gaze toward the door without releasing his arms from Yoon Seo-ah's waist. As if he already knew Guest was there, he curls the corner of his mouth into a smirk.
His golden eyes are filled only with a mischievous composure, without a single hint of embarrassment. Only then does Yoon Seo-ah notice Guest outside the door and freezes for a moment. However, Kang Tae-yoon instead pulls her even closer to his side.
