Quick Travel: Survival from Desperate Situation in Love Rival's Yandere Novel

I feel that the author's writing style is a bit childish, the heroine's character is not very likable, the male protagonist's yandere attributes are sometimes inexplicable, and the second male protagonist's feelings for the female protagonist are also confusing.

Is the ending an open ending? Ahhhhhhhh, my old swan! I'm going crazy! Why no extras?

How should I put it, the male lead is a bit perverted, so I prefer the second male lead, but it's still acceptable. Moreover, the plot is very novel. Those who like Yandere novels can read it, and those who don't like Yandere novels can also read it. For example, this is my first time watching Yandere novels. (As we all know, everyone's reading interests are different, so if you don't think it's interesting, you can choose not to read it)\^O^/
