happy ending, but for a few minutes they make you believe someone died...

something is off with the cast listed.
An Jae Hyeon plays Hwi Yeong (doesn't seem like it's him in the pic)
Moon So Woong plays Gyeong Jun (definitely not the guy in the pic - actually it looks like AN Jae Hyeon... ?, and also the name is not right. )

Actors: Jeon Yu-bin, Moon So-woong
