Why did MengMeng commit suicide in the aftermath?

The reason why MengMeng committed suicide in the afterwave has a lot to do with his parents' education methods. According to the plot of Houlang TV series, I learned that MengMeng committed suicide in the 27th episode. The content is: her ex-boyfriend threatened her with private photos, and her parents kept her at home to monitor her every move, and gradually collapsed, and she jumped off the building.
