FFYC is wonderful! Thank you so much for writing it! I was wondering how you decided what house to put everyone in? What qualities made Yuuri a Slytherin and Viktor a Hufflepuff? I hope you're doing well and thank you again for sharing your writing with us.
I’ve already made a post here about why I see Yuuri as a Slytherin which hopefully explains that part ok!
As for Viktor I chose Hufflepuff for the hardworking aspect (we’ve seen from canon he’s incredibly dedicated to his career and you don’t get where he is without lots of hard work). Other traits of Hufflepuff (from the Harry Potter Wiki) are listed as friendly (he’s a very friendly, outgoing person), loyal and honest (in Viktor’s case sometimes to a fault, he’s very bluntly honest). Viktor as the friendly, cheerful and incredibly hardworking Hufflepuff just really seemed to fit for me.
For Phichit I chose Gryffindor because he’s outgoing, brave (first Thai skater to make it to the Grand Prix Final ever! That takes some serious courage to be the first of anything) and has nerves of steel (we never see him getting outwardly nervous once in the whole anime which for someone competing at his level is very impressive). He has traits from other houses but I thought he fit well into Gryffindor.
Chris came from Beauxbatons so he doesn’t have a house. Technically Beauxbatons supposedly only get students from France, Spain, Portugal, Netherlands, Luxembourg and Belgium but considering where Switzerland is geographically it was probably his closest school and so either I’m just going to use suspension of disbelief or say he was a foreign student.
As for the others, I just see a lot of Slytherin qualities in Yuri, Hufflepuff ones in Otabek etc. Honestly, every character could probably fit every house but I just chose the ones I personally thought fitted the best
