Mo Yutian felt both Little Apple and Little Grape needed a mother right now and they both heavily relied on Jin Xiaoxi. It would definitely be better if Jin Xiaoxi became their stepmother rather than Huo Yunshen marrying another woman.
Moreover, Jin Xiaoxi was also pregnant with Huo Yunshen's child. Once this child was born, they would be able to become a family.
The best thing would be if Little Apple could go back to the royal family. He would even have someone dependable to continue to look after him. In this case, he would also be able to step back after doing something good.
Jin Xiaoxi had been taking care of him all this while so he should also do something for her at the end!
Mo Yutian had already made his decision but Jing Xi was not willing. "How can I do that? Then what will I become? I already said I wouldn't abandon the two of you."
