Park Yoochun lost his fiance on their fifth anniversary. On the road to recovery, he gets an unexpected visit from his late lover's twin, Kim Junsu. P.S. I love you, Junsu is a heart-warming story of how one tries to deal with losing someone they truly cherished and of finding someone you didn't know you have been looking out for.

Abt the trailer: (1) Let's imagine the guy at (00.21) and (1.01) is Yoochun. (2) (1.48) onwards is the probable happy ending or could-have-been ending of this fiction (I don't know since I have not completed the fiction yet) (3) You can ask me anything if you're confused but it's not a good idea since saying anything more than this will reveal parts of the fiction itself.
