The Crimson letters

Every few weeks, a new anonymous letter appears on the crimson bulletin board at Haneul University.

Each one begins with the same words-

To the one who...

No names. No clues. Just a few carefully chosen lines that leave an entire campus wondering who they're about and, more importantly, who wrote them.

What starts as a harmless mystery soon becomes the university's biggest obsession. Every student has a theory. Every classmate is a suspect. And every new letter only deepens the mystery.

When the letters suddenly become more personal, Felix and Jisung begin to notice details that feel impossibly familiar-as though someone has been quietly watching them all along. But with everyone pointing fingers at everyone else, separating coincidence from truth becomes harder than ever.

As secrets hide between handwritten lines and feelings begin to outgrow anonymity, one question remains...

Who is behind the Crimson Letters?
