Is Jin-Woo from Solo Leveling a Bottom?

lmao i'm kidding, i think he's a switch. but my actual question for all of you that read/seen solo leveling [SPOILERS INCOMING]:

What are your thoughts on the endgame relationship/his relationship with Cha Hae-In? I feel like it might've been forced, or at least haven't developed enough? In a way that there's not enough time spent between the two to show enough chemistry.

But that's just my opinion. And for those of you who haven't read solo-leveling yet (the manga or novel): read it! I promise it's very good, and there's a reason why people love it so much. Also bonus points because the MC is very attractive .

P.S. I'm interested in your answers for the heading as well, so answer that if you want to, and tell me why ^^
