I wonder about that. In most manga they would reconcile. However in this one we have a coworker getting divorced and nothing happened when Rika met her father and half sister. At the same time Rika doesn't seem to be mad at her mom. She seems to be pretty emotionless. I wonder if that is just how she is or if we are about to see a dam burst.It was pretty wholesome for Rika to tell her mom she was gonna marry Takuya like that, but then Ritsu malfunctioned and was kinda over the top in her reaction. No wonder Rika was shocked, she probably never saw her mom act like that once in her life.
I guess Komiya's gonna have to help Rika and Ritsu reconcile! I hope she does!
