Unfortunately, they failed to build that chemistry between the main couple. It is mainly because of the male lead poor acting ability and performance. He also doesn’t have the look and charisma on an equal level with the female lead.
Chemistry is very important in romance drama.

This is another of those series that I was rooting where the second male lead gets the girl. LMX has that conflicted, dark but oh so sexy. The actor did a good job portraying his character and he is also quite charming.

Disregard the plot holes, it is a decent drama. OST is very nice especially the ending song.
