Myungsoo gets eyebags so heavy that they're worse than pimples. All because of something that lingers around the air and makes hard to breathe.

The elder chases memories, while the younger loses the sanity.

Sungyeol folds thousand paper cranes to get his wish fulfilled.

His sanity has come to an end. His insanity, though, has just begun.

If it hurts this much, then it must be love.
