They both are problematic. They can fix it by just being open to each other. They protect each other but that protection can also the reason that they will fall apart.looking forward for next episodes.
I am thinking that smile code might be for Gu Yi not for Dai Wen. Gu Yi isn't really a happy person but a type of broken person who hides her pain through her smile. I am that kind of person but I am not sure if that is the same path Gu Yi is. A lot of people think that I am just a happy guy but little they know I am crying in silence almost all of the time and dramas, anime, novels has been my source of happiness and escape from my problems.
I don't know what's on someone's mind that the drama isnt even at the middle yet they put low score. This is more than just a love story for me but rather an emotional and something to learn from.
