The way I see it, it's more about the fact that MC wants to be spoiled in this case? And I love the teacher letting the student lead the way plot
Don't forget that we're in yaoi universe. P-size decides who'll the top, nothing else matters.
There's only specific yaoi like Bara where gravity don't apply lol but clearly, this title is not tagged Bara.
So, my money goes for Guwon to top the teach.
In the korean official site, the author tagged it as #BigTop #ObsessiveTop #AffectionateBottom. But lets see how it is played
A few weeks ago someone asked a question about which tops would we like to see bottom and someone responded to my answer and we came to the conclusion that sex is a power play so basically most tops wouldn’t bottom because they tend to be more dominant than the bottom. Reading this and keeping that in mind, I can’t help but have trouble seeing Guwon as a top. Looks wise he’s your stereotypical top, and there’s a 99.99999999% chance he is topping, but how are we getting there? He’s being written as a blank slate and very, very innocent, almost like a child. In this case the teacher definitely has more life experience, so if sex is a power play, how in the hell is Guwon going to become the more dominant one when his mental age is very young? It’ll be interesting to see how the author makes this character grow and mature enough to take lead.
