She Ran Away from Him and Was Not to Be Offended by Her Sickly Brother

Is this male protagonist really okay? I don't understand the male protagonist's family, why would they adopt the female protagonist? In the early reading, I felt that the whole family was not very welcoming to the heroine. I did not believe that the heroine was a child and he pleased them. His adoptive parents could not feel it. They seemed to treat the heroine with a sense of condescension towards rich people. This sense of overlooking made it impossible for the heroine to live a normal life in their family. It felt that they adopted the heroine just to To show their love and kindness to the outside world, the female protagonist is just a tool for them. When their son, the male protagonist, bullies the female protagonist, they all feel that the bully is not their own child, and it doesn't matter. But when the male protagonist has different emotions for the female protagonist, what they solve is not the emotional problem between the male protagonist and the female protagonist. I wish they solved the female protagonist! More importantly, I think they deliberately guarded against the heroine after they adopted her, probably because they were afraid that she would fight for their property in the future, because the hero and his brother obviously received an elite education, while the heroine seemed to have only received a basic education from the country. In the end, I can only work in a milk tea shop. This is very obvious, because I think if they educate the heroine well, the heroine will not be able to work in a milk tea shop after the divorce. And if they educate the male protagonist and his brother, they just bring the female protagonist along. I think if you encounter a problem, it will not be solved like now.
