Changbin and you were childhood best friends. you guys played together everyday and went to the same school.

But one day... everything changed.

On your eighth birthday, you received news that Changbin went missing.

You cried. For many, many weeks.

Eight years later, you're sixteen in the tenth grade, someone new came to your school. You could swear that it was Changbin...

The teacher asked them to introduce themselves.

"I'd rather not."

The teacher was dumbfounded but just sat him not to you.
