I've seen so many characters act as foils to each other. Now that I write stories, I love exploring how different relationships can act as foils to each other.
Wukong & Nezha / Macaque & Li Jing
Married(n't) couples foils:
Wukong & Macaque / Wukong & Ao Lie
Macaque & Wukong / Macaque & Li Jing
Macaque and Jing are definitely a cat and owner pairing. Macaque tried to pull this with Wukong, but Wukong ain't buying into any of that. Wukong was a bit worried and did have his doubts, but Macaque's random nighttime strolls became so frequent that Wukong grew more tolerant of the wait and eventually learned to live life altogether without him.
Macaque doesn't just pull this sort of thing during the nighttime. He'd do it for hours a day, too. Being gone for 24+ hours was a rare, but not impossible circumstance.
Wukong's job as king, plus having children to raise (which, by the way, you were so close to guessing the number I had drafted for the two) made it so that Wukong ran out of shits to give in that department. He just doesn't have the time or energy.
Wukong knew he wasn't cheating, but some of their kids had speculations.
One of their sons didn't realize Macaque was his father until his late teen years. He thought that Macaque was another random monkey that liked to hang out at the palace. He thought that DBK was his father, which, given that DBK didn't have a spouse at the time and hung out with Wukong and the kids a lot, wasn't a too far out there theory.
It's not as big of a problem now that Macaque divorced Wukong, and all of the kids are grown up (at least the ones that are still alive). Jing's different from Wukong, which allows Macaque to be how he wants with minimal consequences.
This bonus chapter is one of the very few consequences but one that he's willing to work through. He never leaves without notifying Jing and telling him approximately how long he'll be gone and will update + send pictures when necessary.
Jing gave him Nezha's old phone with a new number to stay in contact. Macaque's taken a liking to taking pictures, so Jing got him a better camera.
There's now a room that acts as a photo gallery with items to make scrapbooks with.
Macaque is living his best life now.
