Man! Your AU of GalaxyPeach is getting beautiful and funnier by the post.
So many obstacles to win Macaque's heart proves to be difficult than he thought! It took me by surprise that Macaque and Red Son are related!?
You know, it made wonder how did MK had the pleasure of meeting Monkey King's love?
Sorry if I ask so many questions but I can't help on how precious it is 💕

Oh they're not related Mac was just there when she brought him to the heavens. Mac wanted to help with the energetic fire-child he loves kids and knows how to deal with them and they bonded a lot so much so that Red Son started calling him uncle! Mac was pretty excited that he had a nephew now.
As for them meeting MK and Mac, I haven't figured that out yet. All I know is maybe not until a little later while Wukong trying to convince Mac to come to Earth and hang out a little bit or Wukong trying to see how MK would react with him dating someone and will come texting somebody and not paying attention to MK well training him and MK noticing it. all I know is MK didn't get to meet him or know anything about him until later in the relationship that he gets to finally meet him.
