A few men have a good grasp of the psychology of criticizing yandere. It's just that the heroine's psychological activities are slightly less, and she feels a bit wandering. The tense interaction with her senior brother in the end felt good. The only drawback is that the psychological descriptions after darkening are a bit homogeneous, but the plot is good, taking into account both the main line and the emotional line (the emotional line accounts for the majority).
I watched it overnight and was very impressed. I may not be able to adapt to multiple perspectives and multiple timelines, but the heroine is really well portrayed, especially her strategizing in the early stage, but it is not so prominent in the later stage, which is a pity.
