Masked Villain's Love Rules

The male and female protagonists are quite good. As of Chapter 15, the female protagonist is not considered a villain. She is a bit vindictive at most, but not to the level of a villain. She should be a growth type. The male protagonist is a bit of a middle-aged boy. The female protagonist has a friend who has a lively personality and is a bit of a middle-aged girl. But the settings of the male and female protagonists are too cliche. The heroine's mother is gone and her father doesn't care. The partial step-siblings have been replaced by partial cousins. The whole family does not love the heroine. But when it comes to the male protagonist, even though his mother is gone and his father is not happy, he has a grandfather who loves him. Secondly, the progress of the plot is too slow. Now that I have read Chapter 15, I feel that the heroine is being offended. The heroine's father is too holy. There are four people living in the family. The heroine's father is only chauvinistic towards the heroine and bullies the heroine's baby [almost crying] [almost crying] ● I don't know because he wants to get property. He thinks that his grandfather favors those two cousins, so he treats them well ● Or those two cousins are his illegitimate children ●It's because his cousins' parents were killed by him. He was so kind to his cousins in order not to be discovered. ●In any case, he was not good to the heroine's baby. The heroine really felt uncomfortable watching it [crying][crying]
