It should've been Junseo

I think it was a nice manhwa and I really enjoyed reading it, although I must admit that I find the ending disappointing. The problem that I notice in this work is the character of Karam, which in my opinion was written in a way that prevents readers from making any connection with him, and his interactions with the main character seem to be very limited, I don't feel any chemistry between them. This is a diametrical difference compared to Junseo, who is a complex character, readers are able to create a bond with him and identify with him. While Karam is not a disliked character, the readers' comments speak for themselves and it isn't hard to notice that the feelings towards Junseo are much more positive. Unlike Karam, we had a chance to actually get to know Junseo. Now, when I think about it, I realize that in fact the author didn't tell us much about Karam. As for Karam's relationship with Jaewon, as I mentioned before, I don't see any chemistry between them. They have nothing in common that would allow them to relate to each other, they have no impact on each other. Once again, Junseo is the one who can do all of that. He and Jaewon struggle with similar problems, support each other, and their interactions are not only very interesting, but I think they are much more frequent than those between Jaewon and Karam. As many people have said, this manhwa feels like Junseo is going to be the endgame, and the fact that it turned out to be Karam is simply baffling, not something we would expect. I noticed that there are people who treat it as a plus, they are happy that there is some novelty among the manhwa and there has been no sudden change in Jaewon's feelings, however, I think that such changes should be assessed not only in terms of the fact that it's something new, and also to actually analyze it, look a little deeper than just on the outside. I hope those who choose to read my words understand what I mean by this.

In addition, I would also like to share another of my opinions, and of course I respect people who will disagree with it and see it from a completely different perspective. I would like to say a few words about this realism, which is often treated as a plus in manhwa and other productions. I think this may be a good thing in some situations, but I also notice that when we consume different kinds of stories, we expect it to entertain us, which, unfortunately, realism cannot always provide us. Love in real life isn't at all what books or movies describe, and in most cases there's nothing special about it. Who would like to read about something that doesn't attract our attention? You can try to create a work in which the feelings will be born from the most ordinary situation, without any fireworks or whatever but without any interesting plot twists or interactions between the characters you won't be able to keep the readers' interest. I think this is clearly seen in Unripened Expression as Karam's relationship with Jaewon is underwhelming for most people compared to Jaewon's relationship with Junseo. People prefer what is more interesting and offers something more than what you might experience in real life. I wanted to say it because I've noticed that some people think it was a good idea to keep the story somewhat realistic and write such ending but as you already now I don't think that's necessarily truth.
