Actually, I was stuck on the day when Segi has to visit the boy from her son's class — the one who wants to make her his "wife" (or rather, his plaything). You're supposed to visit him in the room upstairs, where his uncle lives.
She seems to reject him at first, and after that, you’re meant to do several things like looking for her son’s girlfriend and visiting the villain too. But for some reason, I couldn’t get the day to progress. When I went back home, nothing would trigger. I even contacted the developer, but he couldn’t figure out what the issue was either.
In the end, I found out by accident that I had missed triggering an important event earlier — which wasn’t clearly explained in the task list or was worded too vaguely. Once I triggered it, the day finally progressed.
It wasn’t easy to figure out, but I was really glad to be able to continue the story afterward — finally!!
