Nah cuz inseo got the bigger di**

Again ah-juciy better watch out

I can't see Inseo being the bottom with his temperament though. It's subtle but it's defintely established that he's an strict top and when thinking of themselves as a couple that's the dynamic he always thought of. Even in the flashbacks with their kid pictures you can see the hints that Inseo was always going to drive. Yi-Hyeok is a bratty/bossy bottom though. That becomes more and more clear as the story progresses which is why he gets freaked out with the Boss character as the Boss is purely Dominant (and wants a resistant bottom like Yi-Hyeok hence the chase).
