FFS ... *sigh* ... of course add some more pointless drama on top of the pile. This is Mano all over again. Well, if you add in the separation and the cheating this is worse.
Also, I dislike it very much when sexual abuse is tolerated but only from the female lesbian characters in manga. If that was a guy (that forced his way into her room and proceed to have his way with her) people would call what happened in the last few chapters between the girls at the dorm rape. Sexual abuse is sexual abuse regardless of WHO is perpetrating the act. It's even worse that she is a student ... yeah, she is married ... but the characters at the dorm don't know that. The trope of the rapey lesbian should die in a fire. The justification is 'but she is a girl' ... sorry homey NOT GOOD ENOUGH ... rape is rape.
