Heart warming. Sentimental. A story about not forgetting but accepting the past; accepting the goodbyes; accepting the coming and going of things.
Because of this moral and the sentiment of this drama people may find it boring and drop it right after the culprits have been found, but the ones that do really stay, and truly watch and listen may see the actual moral to the story and how sweet the little moments/sentiment in this drama is. ? This is, in my opinion, how the art of this film is really appreciated.
This is just my opinion on the drama so please don't feel offended if this opinion doesn't match with yours.
