I don't think it's that, but he does mention it as if it would be as easy if you were a woman. I mean, that's an uncomfortable position for anyone who's not used to it, if I get like that in a few minutes my legs cramp as well. I think Minjun is being a little too demanding, but he doesn't have that freedom; for someone who was afraid a lot in the beginning, he is acting too casually.
I think Minjun is bit overracting. He being a man should be able to sit without much difficulty. But why they portrayed him like a fragile princess who cant bear to sit even for 30 secs. Thats a bit too much.
