Contract Love, My Cool Goddess

The subject matter of the novel is good and the author writes it well. How can I put it, now that I see it, the abuse is enough, there are too many supporting characters, and there is no description of the heroine's mental journey at all, which feels very abrupt, and the heroine falls in love with the hero. Since it is a contract love, should we detail the process of the contract? We can write more about the sparks between the male and female protagonists, such as the male protagonist's illness and pain, the female protagonist's spiritual power that comes and goes, and the female protagonist having to take care of the male protagonist's life (the male protagonist's troubles when he is sick, the female protagonist's petty temper) "Qi, the male protagonist's care for the female protagonist, the female protagonist's consideration for the male protagonist, a process from caring for each other to letting go." In 100 days, I can write a lot of details of life, and write about abuse and pampering in detail, instead of writing a lot of details about supporting characters. Personal opinion, don't criticize if you don't like it, thank you.
