Dropped after 13 minutes because the FL is a psycho and very rude and annoying. It matches the record held by the actress in Love To Hate You as the most obnoxious female lead in drama for me.
The baby murder got me mad, that woman deserves death. But other than great show. Probs best I seen this year. The music is really good too and an amazing cast.
I like this a lot now that I got further into the show. The FL is amazing, not bitchy like FLs in 90 percent of Kdramas. Great music, cast and interested in the story. Enjoying this better than Parks marriage contract which i am watching at the same time.
The ML is the most adorable actor I ever seen in any drama or movie. This is a very light and chill show, unfortunately i got bored halfway through and had to skip a few episodes to finish it. Reccomend it for easy going , relaxing watch with fantastic music. 6/10.
I have to emphasise how good the music here is. It fits with the show perfectly.
For me the ending wasn't satisfying. For all the people he killed, I think he deserved to ide. Especially for some of the crimes, I don't believe all of the people deserved death. 6/10.
K-Drama 
The omega verse is old to me as I am reading yaoi/shounen ai for years, but it's interesting seeing it play out in a drama.
I have to emphasise how good the music here is. It fits with the show perfectly.
But I think I missed something because how come they didn't turn back to their old lives after a year has passed?
