First off, this drama is pretty mediocre. Although I was surprised that I never heard about it the months following its airing because of how similar it is to other dramas I've watched. Even though it's mediocre, it was somewhat entertaining. The best part about this whole drama actually happens really early on. It's when the FL and ML are on the bus, and the FL tries to take a picture of them both and teaches him the "heart" symbol with the thumb and the index finger, and he asks (paraphrasing) if it means counting money. (The scene is more hilarious than I described it; trust me.) It gets a bit repetitive, and the antagonists are quite cartoonish. Meh. The ML literally did all the heavy lifting of the kisses. He carried them on his back—or at least he tried. As a drama, I give this 3.5 stars... as a show... maybe 1.

The real problem I had with this are the comments on YouTube. I tried to avoid the comments, but after reading some, it turned out really concerning for me. I usually stand from the "entertainment is entertaining" standpoint, so I never focus on how damaging entertainment can be for people that believe it also applies to real life. As entertainment, this was okay. But for reality, I'll talk about what's wrong. The subtitles on YouTube call the FL's illness "PTSD (post-traumatic stress disorder)" when it's actually "DID (dissociative identity disorder)". It's also referred to as "stress disorder". The problem is not only a false classification of an illness, but it's the fact that the people watching it don't know that the FL isn't actually suffering from PTSD. From reading the comments, I can clearly tell a lot of the people watching are young. More likely it's prepubescents, pre-teens, or just teens that have no concept of what illness is being demonstrated. Mostly all the comments on every single episode consist of people calling her "PTSD ability" so amazing, and they love her in "PTSD mode". W H A T ? And then you see them wishing they also had that "power". This is incredibly concerning that they think this actual illness is something playful. PTSD can be devastating. Imagine if those people who may one day meet someone suffering from PTSD and believe it's a cool "mode" they can switch into. It's very ignorant and insensitive. They may react to them by saying what I see in the YouTube comments—and it's not appropriate AT ALL. I'm not sure how DID is subtitled for other sources, but it's a really bad mistake to classify it as PTSD on YouTube. I'm also not sure if in Mandarin they are actually saying "PTSD" and not"DID" since I'm not fluent in Mandarin, only Cantonese.

TL;DR: DID is not PTSD. YouTube needs to fix their subtitles. People that have no info on PTSD, by watching this drama, will now mistake it as a fun illness (a "mode" you can switch into). (Especially and most likely young people—evidence in YouTube comments.) They may tell a person with actual PTSD the same things that are said in the comments of the episodes, which are incredibly inappropriate, insensitive and ignorant towards someone suffering with PTSD.
