On March 17th, an episode of KBS 'Immortal Song 2' showed SHINee's Taemin performed with f(x) Amber.

Taemin and Amber performed ‘Wrongful Meeting' by the famous singer Kim Gun Mo. During the interview before his performance, Taemin stated 'There is a special guest who will help me create a great performance today' and began his performance with a powerful choreography.

The song began by f(x) Amber's impressive rapping followed by Taemin's singing unaffected by his powerful dance moves. The audience went crazy as Taemin and Amber created an unbelievable performance.

Regardless of his powerful performance, he was unable to beat the top scorer. Taemin revealed "I'm discontent because I practiced so hard," and expressed that he was sorry for Amber. Amber then replied, "You're number one in my heart."
