Basically this is a Scumbag x Doormat trope. Doormat has a crush on Scumbag since they were kids before he became a scumbag. Because Doormat believes what he did when they were 14 made Scumbag become a scumbag, he tolerates all the craps that Scumbag throws at him. The craps includes rape and scumbag making doormat sleep with other men because he basically has an extreme cuckold fetish due to the nature of having the origin species of Great Purple Emperor, a highly territorially aggressive butterfly. As I was reading it, I was constantly screaming in my head like, why can't you fucking grow a backbone and leave this fucker? Or, after he raped you the night before and refused to leave your apartment, instead of cooking a dinner for that scumbag, use that kitchen knife that you are using to cut up food, to either stab that fucker, or at the very least, threaten him to leave your apartment. The book is so damn repetitively irritating because Doormat keeps justifying why he put up with all those bullshit and I felt like I was reading the same irritatingly illogical passages over and over again. This book also gave me this weird vibe, unexplainable until I read some Amazon reviews about how the author tried to write it like general novel to follow the footsteps of a couple other popular BL writers who have gone big in general novel space while her writing skills is not there yet (She later did publish a general novel which wasn’t well-received). In this book as well as the last volume in this series, the writing style often feels like a general novel. However, since this is still a BL novel, where happy ending is always guaranteed, unlike a general novel where readers can hope for Doormat eventually being cured of his Stockholm syndrome, and moving on, readers have to keep reading Doormat doing some mental gymnastics to justify why he still loves Scumbag while doddering toward the happy ending. So I just dropped this book halfway through because I can't take it anymore (I did confirm the happy ending by skipping to the end though).
