Listen, them being related in their lore ** doesn't** mean they are a couple by any extent like he's been spamming for ages. That has never been a thing nor would Riot have the guts to try that as it WILL KILL Ahri sales and make people hate Wukong even more then they already did during his short time in LCS. He's only popular in china and while that is their largest market, they wouldn't risk sales globally.
But they ARE listed on each others related champs and had been since the days Riot had a more detailed explanation of what each character was in relation to another (Garen and Lux were listed as siblings, Singed and Yi were listed as Rivals, etc.). Back then they were listed as friends. Not a couple, not married like
and
. JUST friends, but never explained as to why they were, as they were likely holding onto that story for later (like how we found out the reason Ryze knew so many random champs was because they helped him on his quest to find the world runes). by extension, I can say with a 90% certainty that this will stay the case.
No sense in skipping that story to force another "Varus is now 2 gay guys and a darkin" fiasco by making them a couple out of nowhere. Especialy when we already HAVE a Vastayan couple with
and
. There's nothing wrong with them making more canon couples but for them both to be Vastaya couples? unlikely and will come off as a bit forced.
Lets face facts here, Ahri is just WAY too popular of a champ for Riot to put into a relationship with anyone as there are too many people who like her single (looking back at the uproar about her even HAVING a past relationship) and Wukong is nowhere NEAR popular enough to even get close to having that kind of relationship with her. THAT and lore wise Wukong is way too interested in fighting to have a real interest in romantic relationships. Friends? sure. Strong friends present new challenges in combat? DEFINITELY. Romance though? no indication of him caring about that at all.
Friendship wise though yea, with all the stuff Ahri's been through she really could use a good friend who looks on the bright side of things to lift her spirits up and Wukong could REALLY use better people skills in general... like... seriously. I like the champ and all but he REALLY needs to grow as a person, hopefully mature so he can finally do whatever he has to in order to become a Wuju Master. Time for Wukong to become Master Kong already (They did say he could use a title change anyway. Master Kong, the Wuju Legacy could have a nice ring to it after someone workshops that a bit >.>)
But outside of that there is no reason to expect that they caved to make the one ship that would make any Ahri fans blood boil canon.
