Seungmin is your ex, both of you being each other's first love. Your relationship bloomed in highschool and lasted for three lovely years, before he had to end it 'cause he's moving overseas for college.

Your heart broke at the thought of him not being willing to put up with a long-distance relationship to keep you... but a year has passed and you've slowly accepted it. You keep thinking, maybe he's just not the one for you. And you become more sure with that idea when you finally see him around again, but he's acting so cold...

So distant... as if those three years of love meant nothing at all. Seungmin stops by your favorite cafe, seemingly returning for a vacation. He buys a drink and notices that you saw him... but he looks away and sits down on a table as if nothing happened... as if he doesn't know you at all.
