Rather, this dorama is about the changing societal expectations of relationship, the roles of gender, and their interplay. Questions like what does 'to protect the woman' in a relationship or the significance of a piece of paper to define your romantic connection is discussed in modern society where nuclear family is no longer the norm. So, this is not a love story. It's a story on navigating modern relationship, both platonic and romantic. It doesn't necessarily give you an answer but it treats the audience as intelligent and invites you to ask these questions yourself. This is probably one of the most thought-provoking dorama I've watched ever that questions self-love and the relationship without shoving an answer down my throat, which I so much appreciate and recommend this.
