Okay, so, the bad, the good, and the DID.

Let's go in that order. So, the story is essentially about a man with DID who eventually meets a doctor, and one of his personalities falls for her. There is past history and childhood trauma, the whole works. In regards to tropes, this one ticks a lot of boxes, but not in a disinteresting way. The story keeps moving for the most part, and the different personalities make to keep it interesting along the way. There is, of course, a company that everyone's fighting for and this offers some tense exchanges between characters as well as some fun exchanges. Probably the biggest flaw in this was the FL and her brother. The FL can be loud and screamy and though she's numerously pointed out to be a tough character, she often wavers in the face of forcefulness or manipulation. They make up for it in other parts, so it wasn't completely unbearable but I would have liked her to be a bit more consistent. Meanwhile the brother is at times forceful and goes behind her back to what he thinks is right. This unfortunately leads to some tense and frustrating scenes that seemed to have no place except to create extra drama. Despite those annoyances, the skip bar is there for a reason and it's easy to get past those grievances.

Now, the good and the DID. The acting on everyone's part was pretty good, but the one that shined was the ML. Ji Sung delivered a flawless performance as he tackled 5/6 different personalities. If you don't know, DID stands for Dissociative Identity Disorder and generally takes place when a traumatic event happens causing the mind to protect itself. Ji Sung acts as Cha Do Hyun who suffers from this illness and must navigate his day to day life with these other personalities popping out every so often. It makes for some funny and sad adventures. The slow reveal of the story is quite good, and just endure through the subpar CGI as it is a plot device. There were some strings that were left untied in the story, but they weren't super glaring so it wasn't a huge problem. They do address child abuse in here, though it's not too explicit, and I loved how they lightly tackled blame shifting. It was subtle, but it was there and I appreciated it. The OST is AMAZING. I often went back and listened to it over the years before I got around to finishing this, and I still love it.

All in all, a good drama that stays pretty straightforward. I would recommend giving this a go if you're looking for something mildly serious with some romance. Also, just watch for the five different personalities. They made for some very fun and heartbreaking drama watching.
