Ruan Xihan doesn't answer the question of whether anyaki is a good mother. For her, it's just Jin Yanchen's family business, as long as the child is around her
Si Jingchen saw that Ruan Xihan didn't mean to object to Jin Yanchen's proposal, so naturally he wouldn't object to it. He didn't like the woman anyaqi. It's better for Nianhan to follow anyaqi than Ruan Xihan
