24 years ago, in a third-year classroom of a middle school, there was a student named Sehun. As an honors student who was also good at sports, he was popular with her classmates.

When he suddenly died, her classmates decided to carry on as if she was still alive until graduation.

Then, in the spring of 1998, a boy named Luhan transfers to the class, and he grows suspicious of the fearful atmosphere in that classroom. In particular, there is a handsome, aloof girl named Oh Sehun who wears an eyepatch and is always alone drawing pictures.
