He had no feelings for Chen Xi at all. Even the engagement at that time was like a piece of paper.
He expressed his willingness to take responsibility and said that it was up to Chen Xi to decide whether to keep the child or not. He could even give her a sum of money so that she could live a worry-free life for the rest of her life. If she still didn't want to, he could also let her be Mrs. Xu. However, he didn't have the heart to do so, so he couldn't give her the love of husband and wife.
Originally, he thought that Shen Xi would choose to live her own dull life. After all, the two of them had never met before, and suddenly becoming husband and wife was not something worth looking forward to.
However, the reality was beyond his expectations. Chen Xi agreed to get married and promised that she would not force him emotionally just for the sake of the child.
