I think it is a waste of talents. I really like seo in guk in hello monster and park bo young at just anything but this one. I like both actors and I'm just fine with their chemistry, not so much but fine. BUT the story seems going into circle that just can't land properly. Like, anything she choose will be doom so the best plan is to fall in love with him like she can just do that just like that. I remember somewhere he agreed, but then treated or show her how bad he can be. I can't understand why, he like to cease to exist and her plan should be the best. I don't even know when and where they start to like each other, it just happen. Please someone enlighten me, i want to finish it for my love for those actors.

And the second couple is just as weird.
