I binge watched the second season and like you, I absolutely loved the ending! In fact, I’d say that the final episode was one of the most beautiful episodes I’ve seen in a long time, maybe since Mirror of the Witch. Writing wise, cinematography wise, theme wise, I was so pleased with the ending (plus, the relationship I was rooting for since episode one of the first season ended up together, so I was extra happy).
Most of the time, I root for the second lead because he usually cares for the girl in her good moments and her bad, and he actually respects her. I got halfway through Boys Over Flowers and couldn’t watch anymore because I just couldn’t understand how the girl chose the dude even when he was being so disrespectful to her. I guess I’m big on mutual respect and understanding in relationships, and a lot of popular drama relationships do not portray that .
As for the relationship in Cheese in the Trap, I remember thinking that the problem was psychological on the guy’s side. Honestly, I think the choice in the end was inevitable because eventually he needed to work on getting better and becoming a better person. Maybe the relationship wasn’t healthy in the first place, but could that have been the idea that the writer wanted to get across?
Yes, the relationships in The Heirs were not ideal, but I really didn’t take that show seriously. In that way, I could casually choose which lead I liked, not which one was good for the female lead.
I think that sometimes, the fans just go for the lead who looks the most handsome, not the one who would be a better fit for the other lead, in personality, in mentality, and in values. Looks have their place, but there comes a certain point where if someone’s character is awful, their looks cannot save them.
But in the end, they are dramas. Sometimes they exaggerate things, sometimes they try to keep as close to reality as possible.
