I am confused! I cannot say MLs are attractive (my opinion)it does not seem this story could happen in real life, I even must admit that I would not be sad if leads separated and their paths went different directions. At the same time I was watching the story and never was bored. Whereas in other bl dramas we usually have two handsome boys and it is easy to "forgive" mistakes - because they are cute... here, with one lead shown as a king and another - a slave like nerd (I checked - actor is a cutie one, it must have taken a lot of effort to make him look creepy), it take some energy and thinking to understand the real reason they are together. MLs are strengthening each other, the drama shows that heart has its own ways and real love is much deeper than appearance and conventional behavior. Chemistry is on other level, and I can believe that, as after butterflies in the stomach period, relationships must have deeper meaning, such as partner's development, discovery of new personality layers, surprises.
Maybe this is not the best drama, maybe I won't rewatch it and it is not sweet, but was it worth my time? Definitely!
