A week before Taemin’s 25th birthday party he had a concert in Tokyo, Japan. All his best friends attended and unbeknown to them all except Key and Taemin, Baby had also attended.
Key and Baby met up later to spend the evening together when the boys — Jonghyun, Minho and Onew caught up with Taemin who kept their secret. Taemin explained to the boys that Key had something urgent to attend to back home so he had to leave before the concert ended. The boys never questioned Taemin’s explanation.
Away from the concert and by the Sumida river, Key holds Baby in his arms and they chat about their future. Key reveals to Baby that he has no interest in the family business. Baby asks, “Why?”. Key now wants to pursue his old dream of singing. After so long Key had had no focus or direction for anything. But after meeting Baby he wants to sing again! Baby smiles and replies sternly, “Do it! I support you 💯 percent!”. Key kisses Baby on her forehead and thanks her for her support.
