^^I mean if you want my reasoning, there's a few: some voice lines from Arle post-Archon Quest, the aesthetics of red and black mixed with the heavy blue and white creating probably the most easthetically pleasing couple ever, the fact that the characters feel almost tailor made to be foils of one another from personality to playstyle to elements to even height, them being heavily involved in each others stories, me not really having any other ships I like regarding Furina, etc, but ultimately, I think what sells it for me is that they both have this level of theatrics and dramatics nobody else can match. Any serious fanfic between the two plays like an epic drama, because at the end of the day, there's a lot of problems that come with them being together, and seeing how those are over come give some of the best story telling Genshin fan authors have ever done,
