The first time I saw Ji Sung was in Devil Judge, which I ended up dropping about halfway through my watch of it. His performance wasn't the issue, but the story was .. lacking TO ME. I found myself rather bored while watching that one, and that's why I stay away from revenge/revenge adjacent dramas because I know I'm gonna be bored to tears and will not finish it.
Now, I feel the same way about that show that I do about this one and that's why I mentioned it. The premise and story of this show is amazing and I've never seen any dramas about DID prior to watching this one, so I'll give the writing department kudos for their originality and creativity. However, this show is missing something. I'm not saying it's not a fun time because it is. But there is something about this show that I can't quite put my finger on. Again, Ji Sung did very well. His acting was superb; you could immediately pick up on the differences between each personality so I'll give him props for that. However, his co-star was ... interesting. Oh Ri Jin was not boring or dull; she wasn't either of those things but I found that I didn't care about her all that much by the end of the show.

I watched most of this show on mute so the constant screaming that some people have mentioned didn't bother me. However, the character of Oh Ri Jin is forgettable. There's nothing about her that endeared me to her. By the end of the show, I can't even say that I shipped Oh Ri Jin and Cha Do Hyun. The pairing had semi-decent chemistry but the characterization of Oh Ri Jin affected my enjoyment of the relationship/show. I think some people truly underestimate how much the lead character/lead love interest can make or break a show. Or maybe I'm in the minority of not minding a crappy plot as long as the characterization and interpersonal relationships are solid and enjoyable. Either way, I didn't care for Oh Ri Jin. I didn't hate her, but I also didn't love her. She was just kind of .. there. If you're the type of person who doesn't care for the romance aspect of a drama, then I'd probably recommend this show to you. While the romance is there, it's not groundbreaking enough to overshadow anything else and it won't interfere with your enjoyment of the rest of the plot.

Also, how could I forget about her brother? Oh Ri On. I couldn't stand him and I feel like the writers were too sympathetic to him and his plight. Oh Ri Jin didn't hold him accountable for everything he did as much as she should have, and that's unfortunate. Then again, there were many issues with the characterization of Oh Ri Jin to begin with and her relationship with her brother was definitely one of them.

I got to the last three or four episodes before I started fast forwarding through literally everything. I was just so ready to finish watching this show. I'd grown weary of watching this show and I just wanted it to be over! Also, I feel like those last 3 episodes were incredibly rushed. I feel like the show would have benefitted from gradually convincing the alters to reintegrate with Cha Do Hyun. Some of the alters were clearly ready to go, like Perry Park for instance. He should have been reintegrated 10 or so episodes before the ending, if you ask me. It was unrealistic to assume that all of his alters were willing to disappear all at the same time like that. Some of his alters clearly had the temperament of never wanting to leave - Shin Se Gi, for example. He should have been the only one they kept until the end, because it was clear that he never wanted to leave and wanted to experience life for himself. Things were just wrapped up too nicely at the end; it was almost TOO convenient and TOO clean, in my opinion. It's almost like the writers lost their way and didn't quite know how to end this show, so that's how they ended it.

It was an okay show but I feel extremely strange about this one. Hence my writing a review for it. For the most part, I don't like to review most of the media I consume unless I felt an extreme urge to do so like with this one. I highly doubt I'd revisit and rewatch this one.
