AU where, when Shane is a youngish teenager, David and Yuna decide to spend the summer helping their relatives move to Korea for a work opportunity. Shane has a great time hanging out with his cousins, eating delicious off-season food, and generally relaxing in a country that doesn't give a shit about Canadian youth hockey.
It all starts to go wrong (for Shane) when due to a series of hilarious (not for Shane, but for everyone else) misunderstandings Yuna signs Shane up for a K-pop idol trainee class, thinking it'll be fun to try something new while he has a little time off, and maybe it'll give him some confidence off the ice, help get him break out of his shell a little bit.
Unfortunately (for Shane, and everyone else in the class) he 1: actually has a phenomenal singing voice, and 2: he’s so competitive about anything physical that he ends up picking up choreography really quickly and then ends up so bored while he waits for everyone else to catch up that he puts his own flavor on the moves and accidentally develops his own style. With those two factors on his side his natural awkwardness is perceived as a persona, and he’s quickly tagged as The Sweet Shy One. Basically, through absolutely no fault of his own, he blows everyone else in the class away and impresses the instructors so much that they beg his parents to let him audition for the entertainment companies.
There is a world in which Shane is able to put his foot down right there and stop the madness before it goes too far, and the events of heated rivalry proceed as they do, just with the pictures and video proof of this time in his life weighing down his Damoclesian Sword of gayness
Yuna and Shane get stuck in a miscommunication doom cycle (you know that thing they do where she thinks he wants this because he thinks he'll disappoint her if he doesn't, but she only wants him to do what makes him happy, but it's impossible for him to know what that is because he's focused on making her happy) that results in him changing the entire trajectory of his life and becoming an honest to god K-Pop megastar.
Bonus points for this outcome, because in this world Sveta becomes a huge METRO-$ stan, and through friendship-osmosis introduces Ilya to his latest and greatest obsession: Shane, the Sweet and Shy member who doesn't date because he's saving himself for marriage.
God help poor Shane (who spends his life surrounded by screaming girls he doesn't want and skinny artsy boys he is not attracted to) when Boston Bears #81 (a hockey player he is equal parts jealous of and dangerously hot for) starts to pursue him like a dog in heat.
