Cute, cute. So, how will MC deal with FMC next time he sees her interacting with another man? Stab her or will suffocate her? Like yes, FMC is quite a shitty person and has done some fucked up shit, but MC literary was a scary type of simp, and from the foundation of the story (revenge plot) we can see that MC still stays the same.
PS: This story is especially scary for me because I watched a few hours of content from a simp about his favorite streamer. And with each part, it was becoming scarier and scarier. By the end, I was actually expecting him to make a video from outside of her house. This story is important because MC in this manga reminds me of him quite a lot, from "kindness" to "revenge"(tbf revenge here is a little more justifiable).
