rat chaos's Manga

i love the female lead but she's really like maybe he's a good person after all!!! Like sis just bc he secretly hates killing people doesn't erase the fact that he does it as a living and does so indiscriminately. Like he was gonna kill YOU remember??? innocent people died bc of him! So yeah i wish that part of her was a little more fleshed out.... Male lead is excused in the story constantly for his atrocities, but i guess this is a shoujo manhwa so why am i worked up about the portrayal of war?
