Every night , she writes letters to someone who will never read them.
Letters about her dreams , her fears , her loneliness , and the feelings she keeps hidden from the world.
A t the top of every page, there is always the same name.
Dear Jihoon...
For years, those letters remain locked away inside a blue notebook - a place where she can be completely honest without fear of being judged.
Until the afternoon.
She accidentally leaves the notebook behind in a small cafe.
And the person who finds it is none other than Jihoon himself.
What starts as a simple attempt to return a lost notebook soon turns into something so much bigger.
As Jihoon and the rest of TREASURE become drawn into the world hidden between the pages, they find themselves laughing, crying, and worrying about a girl they've never met.
A girl known only as "A".
But when the letters suddenly stop, the member realize that finding the owner of the blue notebook is no longer just a curiosity.
It's become promise.
A promise to find the girl whose words changed their lives.
And maybe, along the way, discover that some of the most beautiful stories are the ones written in blue.
