I don't really plan on watching Arcane, idk why I just don't really plan to, but just from what I've seen Jayce and Viktor love eachother. Take that love how you will, platonic or romantic, but they love eachother and its cute.
Also want to add, one of the people working on the show said Viktor was Ace and I just want to say you can still fall in love with someone and be Ace, you can also just be AroAce.
My headcanon is they love eachother and don't realize how much until the end. "He's like a brother" homie I said something similar about my husband when we were young and it wasn't until we were adults that we realized we were“oh shit I LOVE love you” romantic, also everyone knew before we did so ya. Also I’m Ace af so HAHAAA!
Im sorry, I found that "The Line" song from the show and these two have been living in my brain rent free and I keep crying about them. Also lowkey added them to my OCs world cause there are interdimensional/multiverse travel shit and I want them living there happy and gay.
