Jinwoo's heart has never beat in the 17 years of his life, yet someone makes it beat for the first time

All the moments of his life, sad and happiness could not compensate for how it was to end. Years of living whittled down to a trail of scrappy body parts inside a stomach of a beast. He had no thoughts. No memories. No pictures of better times to steer him through his final moments.

Jinwoo was sure that a ghost possessed Mino's body, because there is no way Mino would doing this to him, no, not in a million way.  

The end of Mino's sanity happened when he learned that things aren't always what they seem. Or after witnesses a very lovey dovey acts between his mat-favorite-hyung and his other weird one.
