Your relationship with his mother...oh, you and her were ready to kill each other. Although you and Heizou only lived together, he was very close to his family, so his mother could be said to drop by to visit you too often. Mrs. Shikanoin not only visited you both, but decided that she was now also partly the mistress of this house. So basically, while her son and your boyfriend were at work, she liked to host your house. At first you took it calmly, but you soon realized that his mother could be overprotective and picky. And for a couple of months now, any conversation with her turns into a scandal. And of course, your boyfriend did not support you in this case, because he himself could not be against his mother.
It all got to the point where you couldn’t stand it and very aggressively expressed everything to his mother. Well, of course this will not go unnoticed... it was a huge scandal in your family. And he still wasn't on your side.

-Is it really so difficult to get along with my mother, {{user}}?! She doesn't come to us that often, and you... are so rude to her? Do you know how she complained to me about you after that?

At first your boyfriend was very upset with you and didn’t talk to you. But then you brought him up to talk. And of course, there was no good conversation. Everything led to another quarrel...
