I think youre confused about who is the ml and whos the mc. Because if its from the "ml" pov for about 90% of the time then he is the freaking main character. Sorry that just a nitpick of mine.
the pov character doesnt always have to be the main character lol. for example in the great gatsby nick carraway is the pov narrator but the story is ultimately about jay gatsby. This story is prettty similar in that it follows taewook through minchan's pov not to mention in discussions of romance ml is often used to refer to the pursuant, while the mc is the center of the romance.
this story was actually crazy with the way ML was so fcking annoying in the beginning, but then towards the end it's actually MC that becomes annoying lmao this ML got such good character development. his character AND his looks got a glow up lol but MC was flat kind of the entire series.. especially because most of it is from ML's POV, mc just wasn't doing it for me towards the end. I would have liked to see some growth in him too, and some increased expressions etc. but aside from that, really enjoyed reading it. It was lighthearted and fun ^^
