X and Y: The Missing Variable

This is a story about a girl who suddenly disappeared after breaking up with the boy she dated for five years. No one knows her reasons nor even just an idea as to why. But the boy surely would like to find it out no matter what.

Will the girl still be able to keep her secret when they cross paths once again?

The setting of the story is in South Korea so you might be able to read some romanized korean words.
