After witnessing the death of his beloved Chris from a gunshot wound, the heartbroken actor Foam is given a pocket watch that allows him to go back...

After getting drunk at a birthday party, Foam gets caught up in a murder case and ends up meeting a mysterious man.

Foam travels back in time to a moment when he still hadn't met Chris, so in order to get close to Chris again, he starts working at the bar.

Ta doesn't take Chris' reminders at work seriously, which makes Chris very angry.

Ta is injured trying to save Chris; Park and Bew spend an unforgettable night together after an accident.

Ta gets his hands on a USB flash drive and thinks that a secret about Chris is hidden inside, so he decides to crack it.

Ta sees someone visit Chris who looks just like the former's ex-girlfriend, which makes Ta uncomfortable.

When Ta faints for no apparent reason, Chris takes on the role of caring for him while telling him something important.

Ta is scouted by Boo and starts attending an artist training program, while Ta's busy life also creates distance between him and Chris.

In order to seize confidential information in Chris' possession, a group of thugs kidnap Chris' niece.
