Spoiler!
Spoiler text.sed on the search results, the MC ends up with Moon Emperor Yue’er. This is mentioned in multiple snippets, including one from r/noveltranslations on Reddit, where a reader comments that the MC is already married to Moon Emperor Yue’er by chapter 250.
There is no mention of the MC ending up with Yue Ling, who is described as a “baddie” and someone the MC didn’t give much attention to after faking his death and returning with a girlfriend (Moon Emperor Yue’er).
It’s worth noting that the novel seems to take a galactic turn, and the MC meets Moon Emperor Yue’er after leaving his home planet. This suggests that the romance develops in a new setting, away from his initial life and relationships.
Just here sticking around.
