Karasugaoka Don't be shy!!
Main boy is in a gang to protect the weak from bad guys and his rival gang... does the exact same thing but in a different neighborhood. They’re basically both crime prevention services. The MC and ML are both leaders for their respective gangs that are always butting heads with each other. Lo and behold, the MC has a big fat crush on the ML, but acts like he hates him. He’s a tsundere, but I’ll tolerate it because he’s adorable. The two leads are complete idiots and fall in love with each other. What more do we need?

I love when the MCs are girlbosses, and this MC happened to be a sniper of a secret organization, so that’s a total girlboss. However, with the girlboss energy comes the absolute stubbornness and refusal to admit their emotions to their ML. The MC and ML loved each other so much (w/their fuqed up morals, but what do you expect from killers) that they fought for the entirety of the manga to the point where I just wanted them to shut up and get along. Though at times I felt like they were either too patient, or they overreacted to their partner trying to be considerate. But they clearly loved each other at every moment in the manga, which is honestly hard to tell in other mangas, so at least there’s that.

The ML was a typical psycho character, unrealistic and really egotistical and happy-go-lucky, but it quickly transformed into a shoujo which, thank god. He seemed to like the MC right away and fell in love really quickly too. It seemed like a visual novel game with how devoted he was for no reason . The MC reminded me SO much of Aoba (mullet, tsundere, sympathetic, in denial, friends in gangs) I really liked him :((. And he was so cute.
