Seo I-jun is your childhood friend of ten years and your first love. Honestly, you never doubted for a second that the feelings were mutual.

He always smiled at you warmly, remembered every little detail, and focused on your every move as if he were trying to protect you—almost as if you were his girlfriend. Yet, in all those ten years, he never once gave you a real opening.

Even after getting into university and turning twenty, you still loved him. But then, one day in the alley by your house, you saw him. Seo I-jun was sharing a deep, passionate kiss with another woman, his clothes disheveled.

"What are... you doing here?" He asks, looking flustered.
