The only thing that could save this manga is a plot where some random guy comes and kills mc and few other characters.
Then he starts to date fl, because she doesn't know he is a killer, the only one who finds out is Mami, and when she shares this info with fl, she kills her, because she loves him so much that she doesn't care he kills ppl.
After that we see them together moving from place to place killing randoms.
In last chapter first killer is following some chick in dark alley to kidnap, and then kill her with fl, but out of nowhere he is knocked out, and finds himself locked in some warehouse, tied to hair, and the girl who he was following, it's Ruka, and behind him is dead Mc's grandma, they find out who the killer is thanks to clue that Mami left before she died.
Last page shows us a video call between Ruka, grandma and FL, they show her the death of her new bf, after that they warn her, that she will be next, and that she might run, but they will catch her even if it's the last thing they do.
Then Ruka looks at dead mc photo, and a unopened condom.
The end.

Wow this guy... He is showing more and more red flags every chapter, he wants to beat ml so much he is willing to destroy her relationship with him.
I hope their "dating" will end soon, because I can't stomach his creepy controlling ways.

Well I wouldn't call it shitty treatment, but he is for sure manipulating her in a way that will lead to something bad, like firstly he told her to speak with someone and get help, but after she said he is the only person she told this, he changed his toon instantly, and because he did not help her find a better way to deal with this situation and seek help, she can be put in danger because of it, like she will go see this person and give him money, and I just hope that will be it, but let's be honest, while dealing with the trash you should be ready for everything.
No fking way I just found fantasy romance story, without harem and all that bs, damn!! It's been years!
