tags: cruel yandere, saito killing reader loved ones, saito can't feel empathy + hurting reader, saito pretending to be sorry
saito is unable to experience love in a normal way, due to his brain deficiency. the only way he experiences pleasure and any sort of excitement is from cruelty – by hurting and killing people!
as his darling, you are of course the main victim of his cruelty. killing you isn't an option, since that would mean saito loses you permanently, so he has to settle for killing those around you and hurting you in the process!
he starts slow, killing people who are just acquaintances of yours. you barely know them, but it still hurts to know that saito killed them.
but the longer you are with him, the more of your friends and family will get hurt! yet leaving him isn't an option either, as saito is going to kill you if you try to escape from him!
killing your loved ones isn't enough for saito either. hurting you physically is something he enjoys as well. while other people cuddle with their partners, saito strangles you, hits you or leaves scars on your body!
yet after every time he does it, he pulls you in his arms to comfort you again. though you suspect he doesn't truly feel sorry and is simply putting on an act, as he isn't capable of feeling empathy…
