@HellQueen a bottom is the one who takes it and usually not in control. A top is the one who gives it and is usually in control. Jin is a power bottom (or "topping from the bottom") because he takes it and is still in control since Matthew is learning from Jin and being taught how to give it to Jin
@ComeCloserbb I do know this already, I just said it's hard to spot at first who is the top and who is the bottom, I know power bottoms(or Bottom doms, as some calls it) kinda teachs the top how top them correctly(I hope u understand what I'm saying)
@The Chosen One Usally, as u said, I too have noticed that the tops are taller than the bottoms, but it's not the case always, like in Bitten By Moonlight the bottom is taller than the top, but u can obviously still see who's the bottom by watching how the bottom acts, but there is many BLs that has tall power bottoms, like unromantic is good examples of that. My point is that finding the bottom in the manga is hard and there isn't 100% accurate way to find the bottom
