yuri being mesmerized by xinlus beauty when he was younger in a non-sexual way is fact. And theres nothing weird about saying that his first love started with being mesmerized by someones beauty, because everyone has their own way of liking or loving someone. In Yuris case, Ive read the novel, and it’s very clear that hes simply not the kind of person who would have thoughts like that

ok i love them and i always thought of Gabe finding young xinlu mesmerizing in a purely non-sexual and like staring at a Greek statue kinda way but why would he call him his first love? it's a bit icky no? they would've been a young child and an actual adult at the time so i just find it odd.
