If I remember correctly, she does try. All but blondie are reincarnators. That friendly guy is the one who doesnt try to kill her. The heroine used to be a japanese man, si he/she likes the protago and tries to get along, but the others get in the way and there is even one who tries to ''get revenge'' for the blondie servant.
Honestly, I think that if you do something bad, you are in for a punishment unrelated to sex. That's what I think. But trying to kill a girl for whom you do not know and has no actual rpoof that she did anything wrong (come on, they are in that world for years already, they should have realized its already reality) and has no means to defend herself, is pure cowardice as a man.
There is only 3 reincarnated characters, this friendly guy, the heroin (a guy in previous life so he is into girl lol), and the friendly guy's brother (was actually his sister in previous life, who tried to kill the mc at first because she think the mc is still bully Ashley, later on tell who is the hidden char). Mc end up with Ash ╮( ̄▽ ̄)╭
He's about to declare her his rival for the love of the heroine
