Mono is a cuckfag of the highest degree but it's somewhat deserved in this scenario because he behaved like a sociopath and cheated on kat.

>kat tells us mono never makes her cum (lol)
>kat posts on chasergen if there are any hot, tall men in europe
>kat posts about missing her ex from 2 years ago calling them the only person she ever loved
>kat posts in this thread that she is unhappy and deranged (mono doesn't fulfill her)
