Yeah. I also feel the same. But, it's a rather lackluster script, if you ask me.
But, this is how c-drama works. It's very hard to find a splendid and good drama nowadays. That's why I always end up dropping dramas, especially modern one. They tend to be draggy and always dilly dally the relationship of the main leads. To me, it's very infuriating. Can't they just speak out their feelings openly?
