ML is a diagnosed psychopath, so he’s not necessarily “crazy” about MC in the usual sense were used to, but he is definitely possessive of him and doesn’t want anyone touching him, so he’s beat up some people and helped MC get revenge on some guys that raped his sister, so he did also kill for the MC.
i need yaoi where the seme literally kills or beats someone up for the uke. like the seme is kind of crazy over the uke or viceversa.
