Kim Seungmin

Who would say that your life can fall apart because of a simple letter?
Well, that happened to you, but let's go back in time.
As far back as you can remember, you're a girl who's always in love, and when you don't know what to do with your feelings, you write letters, which are your most treasured possessions.
And among them all, one name stands out.
Kim Seungmin
He's one of those guys you write a love letter to, a letter he'll never be able to read.
Until that horrible day
It was during physical education class; you were doing the exercises when he appeared to talk.

"Hey... Can we talk?"
You said yes instantly, until he said the following
"Look... I don't know if I feel the same way as you and..."
At that moment your body tensed up, you lowered your gaze and saw the letter
That damn letter
(How will your story continue?)
