Dressed as a Yandere Heroine, OOC Warning

(In the early stage, the girls lived together in a "warm" campus with pure love and daily life, and in the later stage, they had two-way redemption) Gao Jia, a high school student, opened his eyes and became a yandere heroine. In front of him was a gloomy girl imprisoned by her. There is a system in my mind that constantly reminds me that there is something wrong with the plot. Is it true or false that I will die if I don't complete the plot... Gao Jia had no choice but to start following the plot, but something seemed not quite right as he walked along? Why did she start to get hot on the bed of the wife system? If her wife is good, she will pretend to be good. When his wife was misbehaving, Gao Jia "coerced and lured" her. Afterward, he said: "Wow, oh, oh, oh, oh, my wife, I actually have a second personality." (Contains some sadistic emotions, and there are some "surprises" in the plot. Thanks to the little babies for reading. Every reminder is my biggest motivation to write!) Note: Some of the plots in this article are a bit dark, and both heroines are shown in white and black, so please don't read if you mind.
