An idea I’ve been kicking around while waiting for the final episode but
once Viktor and Yuuri retire (for real real. I feel like they’ll be the Peyton Mannings of ice skating) they move into a little house back in Hasetsu and visit the Ice Castle from time to time to skate together. The triplets let them have the rink to themselves before they open on the weekends.
Hana is a young skater who trains at Hasetsu and dreams of competing but her family doesn’t really have the funds to get her proper coaching, so when Hana sees these two skating she insists on them coaching her. I feel like she wouldn’t exactly know WHO they are for a while (until everyone swarms them at her first competition like HOLY FUCK IT’S VIKTOR NIKIFOROV AND YUURI KATSUKI) bc to her they’re just the disgustingly over-affectionate old couple who live by the beach with their billion poodles. Hana basically becomes their unofficial granddaughter.
I guess this AU-thingy is called Hana!!! on Ice
