The original FL wasn't even a factor in the story after the first 50-60 chapters, she was sent abroad & briefly made a reappearance later on. Also, the ML himself was barely mentioned throughout this novel, hence the reason why it wasn't clear until the last few chapters who it was. He's literally missing for 20+ chapters at a time, and the MC spends almost all of the novel disliking/barely interacting with him. Not that any of the other "possible ML's" stood out much either, because a common theme in this novel was to introduce characters only to completely forget about them until they were needed again, I.E. disappearing for 10+ chapters.

Honestly I had a huge problem with the fact that the ML is the ex-boyfriend, there's no doubt that this would've been my biggest issue with this novel, however, the romance had no development AT ALL and was basically just sprung on you in the last 3-4 chapters. Although the ex being the ML sounds obvious given the synopsis, since he rarely appeared in the story it wasn't 100%, and I had hoped that it'd be ANYONE other than him. This guy was obsessed with the FL on a very disturbing level, he had a creepy room in his house dedicated to the FL filled with things she used (keep in mind that they had been broken up for years when she found the room), seriously she broke a vase while in his house and he was gonna put the broken pieces in the room when the FL caught him. This guy even went as far as holding the FL captive once, and full-on kidnapping her another time! Not only that, but the ML ended up spending 4 years in jail at the very end of the novel, only to be released in the last chapter. He was manipulative and toxic, and I still don't understand how the FL ended up reciprocating his feelings after everything that happened!

she didn't just ML but the other way and MC has a big grudge against him and even hit him till he was bloody. But it doesn't mean he is out of the game. It's still unknown who is the ML. There are 4 including the novel ML have an unhealthy attraction to her. And there are another two who are attracted to her but no presence is strong enough to be identified as the ML. The only ones who could be ML is the first mentioned novel ML and a mysterious guy from a organisation but I think both could be the same person. At least MC has good friends and even female friends and there are not many annoying female antagonists. Even antagonists are not easily removed and they are no cardboard characters.

Annoying thing is the author using a whole long chapter to describe the released movies in the novel and other things. MC is strong on her own and has a strong little shota who is like a puppy.
