The ending is very slow and the stage of grief is realistic in it, it doesn't matter if many viewers don't like it, who doesn't like a happy ending? but if you understand the meaning of the ending, yes definitely yall being grown up and understand nothing last forever in this life, this drama is very good and nostalgic! I like it! beautiful yet tragic for the love story but, beautiful for the achievements of the characters. it's depend how you highlighted moral of this drama, what's your highlighted? the romance? or... slice of life?
