only problem with this one is the trope of a man having a love interest far too young for his age.
This isn't a romance manga by any means, but it is implied that there are feelings between an adult man nearly 30, and a teenage girl, which is just gross.
abusive boyfriend literally gives guy ptsd, expects anal even though it literally traumatized him and sent him to the hospital.
But because he is pushy and the other guy is weak, they fall in love and open a business together?
Ew
