I do think the age gap argument is valid, although everyone is older than Yuuri by many years, Wolfram has the mentality of, and is basically, a teenager just like Yuuri, while Conrad is an adult… and his "godfather"
That's fair, although it's still funny when they refer to Wolfram as 80 and Yuuri as 15
May I addressed the age gap between wolfram and yuuri basically in the world 'earth' while we witnessed in the first chapter yuuri suddenly appeared in the different world and the time he went there was a lot of time but when he came back to the original world which is earth the time only minute had passed so wolfram is still young while conrad stay in earth for many years and absolutely experienced being adult and he's basically adult hays please understand yuuri refer conrad as 'he's like my old man' so we can see here that he perceived conrad as his father more like godfather since he named him and js bcs he has the soul of conrad past lover doesn't mean you can necessarily ship them js it's indecent to ship those two no offense.
Please read the light novel
It's been like, what, 2 decades? Can we please shut up about Yuuram vs. Conyuu alr :v
Also Yuuram shippers hating on Conyuu because of the age gap is so funny :) I always get a chuckle out of that argument lol
