No i am actually correct. (@Natural is correct too -sorry trying to tag the person on top and it Tagged u)i understand the mix up for u . it seems alot of ppl dont know the correct terminology for Yaoi and how u cant apply Normal ML and Mc to yaoi. Let me explain
Sorry if its a little long i normally dont explain but in this case i feel i should.
Again u have to remember this is Yaoi:
MC stands for "Main Character," and in the context of yaoi, it’s usually the more passive or submissive character, often referred to as the "Uke" in traditional Japanese yaoi terminology. However, MC is a more neutral term that just refers to the character whose perspective we see the story unfold through. But in yaoi it also mean the Bottom which is also known as Uke .
But here’s the twist that i feel u got confused at regarding MC : In this case, it’s actually the seme (Mok) who is the main character in terms of the story’s development.
BUT Even though the story is told from Mok’s point of view, he takes on the title of ML (Main Lead) because he’s the Top in the relationship. The plot revolves around his development and his relationship, and as the dominant partner, he naturally holds the role of ML,thus it kinda over rules. even though the story is centered around his perspective. So, despite the narrative being through his eyes, his role as the top in the relationship gives him that Main Lead status, even though the other character Nanjo can be considered a Top too but in his relationship he is not that he is (the "bottom" or Uke) the more passive one
Hope this clears up the confusion! It’s understandable why things can get mixed up since there’s a lot of fluidity in how these roles are defined. The important thing is that Mok remains the ML because the story revolves around him and his arc, even if Nanjo is the MC -terms of being the more passive .

Though i don't rly get your understanding of how the terms are used (you said it's based on who's top, bottom, passive). From my understanding, it makes sense that both Mok-yeon and Nanjo are both Main Characters because the plot mainly revolves about them and it also makes sense that Mok-yeon is the Main Lead because his POV is what we get to see most in the duration of the story. Like if Mok-yeon was a bottom and if Nanjo was a top i think Mok-yeon would still take the title as Main Lead.
Reject him(ML) , maybe Nanjo(MC) mind is clouded, thinking Mok-yeon (ML) is just playing with him. But at one point, Mok-yeon bares his truth, even if it’s a roundabout way. It’s clear to both of them! U can tell in there stares and silence.
Nanjo (MC) has so much pride in being right, he can’t let go of it even if he is wrong.it goes to show how damaging he can be to Mok-yeon(ML) too always being put as the bad guy when hes trying to be kind too.
Mok-yeon(ML) at the end, is losing it u can see it . He’s desperate for Nanjo’s love, willing to risk everything, to be vulnerable even if it means exposing it in front of Sunwha(twink) for the sake of making nanjo also honest with himself but that might be a big risk since nanjo fears this realization that his relationship to sunwha wasnt as deep and real as he made it out to be .The real question is, can Nanjo be truthful with himself and admit what he feels? Ugh, the tension is killing me!
