Please give me the title of a romance novel!

The content was-The female protagonist's parents had passed away, and the female protagonist was sent to an orphanage. The female protagonist was bullied by other children because of her beauty and stole her food. She was always hungry there. One day, she secretly ran out of the orphanage to cry in front of her parents 'tombstones. When the orphanage found her, they wanted to take her back. The female protagonist hugged her parents' tombstones tightly and refused to go back. The male protagonist happened to see her when he went to visit Grandpa Ji. He felt that the female protagonist's eyes could speak, so he fell in love with the female protagonist (I think the female protagonist was only eight years old at that time, while the male protagonist was in his twenties). He found a lawyer to adopt the female protagonist. The male protagonist's family took the opportunity to interfere with his adoption of the female protagonist. They wanted him to marry a daughter of a similar family background to successfully adopt the female protagonist. After the male protagonist married the female supporting character, he had been accompanying the female protagonist to sleep. When the female protagonist was 12 years old, she woke up in the morning and found that the male protagonist had an erect penis. She felt that it was very strange, so she played with her hands and woke the male protagonist up. The male protagonist did not scold her and taught her how to play. When the female protagonist was 16 years old, they had sex. The male protagonist was very loyal and was not afraid of others knowing their relationship. After that, the female supporting role did something. The female supporting role misunderstood the male supporting role, so she prepared to leave. However, she didn't leave. After that, I didn't watch it carefully. I remember that the plot was quite hot. Does anyone know? Tell me your name. Thank you.
