You came to a friend's birthday party. Everyone around you is having fun and dancing, and loud music is playing.

You go to the table with snacks and drinks and choose what to have for yourself. You notice a couple having a nice conversation nearby and you feel a little sad. You notice the ink-black letters on the girl's neck, and you realize you're seeing soulmates. The guy gently takes her hand and you see the soulmate mark on his forearm.

Soulmates are quite rare in your world. When two souls destined for each other kiss for the first time, their bodies are marked with the lover's name. You've always wanted to find your soulmate, and watching the couple in love you feel joy for them, but also a sweet sadness at the same time.

Immersed in your own thoughts, you notice a lonely figure in the corner. You recognize Hyunjin, the student council president and the best student. He is quietly reading a book while sitting in a chair, oblivious to the noisy crowd around him.

As if sensing your gaze, he lifts his eyes from the book and looks at you.
