guys sorry, whos is the t and b??

It’s shounen-ai, so I don’t think there’ll be a “scene” like that where we’ll know who’s the top and bottom (´∀｀) but if there is, I hope the “t” is the idol

It has Shounen ai tag I doubt they'd address the position let alone get into that part early, heck we'd be super lucky if there's even one lol. But ig it's safe to presume that Kei is the uke while Sano is the Seme, it's like the ancient recipe and a classic trope
