I find this interesting, I'm starting to like it every chapter. IDK, I just find it entertaining and a good read to pass the time.
Those that are complaining about the manga, just stop reading it if you dont like where it's going or where you THINK it's going. It's just a fictional story, and IRL cases similar rarely happen that often. And yes, we get it that it's an unhealthy and odd relationship between the two, you guys dont have to keep repeating it, we can see it plain as day.
Sorry, just a little rant as I keep seeing in other comment sections, including this one, that people keep complaining about *insert manga name here* are very unsavory and are "trash", when you know what you were getting yourself into by the description and readings of the first few chapters.
