Started out not so great but episodes 5-7 were the best and I felt were acted out the best.

Storyline - the synopsis was a bit misleading where the, “they both have bad reactions to alcohol so they avoid it”. It did not seem well written or acted and their “reactions” seemed like any normal peoples reactions to it. Also, how does the FL “avoid drinking” when you clearly see her drinking on her own and so on. It was a bit misleading. That being said…

It was an interesting and different storyline from most of the CDramas (and web dramas). I think that some parts were lacking in both script and acting. It did not run as smooth as it could have. Parts seemed to be a bit chopped off. For instance… episode one, their so called bad reaction to alcohol landed them in bed together and then nothing after that. Like it was not really meant to be there but they threw it in on a whim. It was not needed unless they were going to use it as someone caught them and made them marry etc… But nope they moved on and acted like it did not happen. I was a tad bit stumped. I could pick the drama apart but I am not going to because I did actually like the drama even with all the flaws.
I really liked that the FL did not back off on the mother when she found out what was really going on. She stood up to her and told her she needed to stop treating her living son like her dead son and let him live his life as himself and love him for who he is. It was one of the best scenes emotion wise.

Acting/Cast - I liked the cast. Sometimes I think the ML needed a bit of loosening up. He did not play both parts as smooth as I would have liked, especially transitioning from one brother the the other. The FL… sigh… the crying. Lol it was a bit much haha (my husband kept looking at me funny when she cried lol). But she was also the same in acting skills.

Rewatch - Ya, I more than likely would. Maybe not as much as I would my other CDrama favorites. But I would watch it again.
