Which romance novel had a male protagonist who was emotionally fragile and afraid of losing the female protagonist?

I recommend the book "Loving You Without Regrets" to you. The moment the male protagonist, Dongfang Haochen, saw the female protagonist, Mo Qingxue, he was certain that this woman was the one he wanted to spend the rest of his life with. He tried his best to get close to her, but one day, she came knocking on his door. It would not be so easy for him to escape. From then on, he began his long journey of spoiling his wife. However, this woman who looked gentle and quiet on the surface was really not so easy to deal with. The male protagonist doted on the female protagonist very much and felt a sense of security towards her. He was afraid that she would leave. I hope you like my recommendation. Muah ~
