The two idols covered legendary trot singer Tae Jin Ah's "Not Anyone Can Love", battling against Ulala Session's cover of "Sorry I'm Sorry".

Eunjung and Hyomin said on stage, "We'll greet you in the girl group way. Hello, this is T-ara... We worried a lot about whether we'll be able to follow Tae Jin Ah sunbaenim's emotion. To be honest, this is our first time on 'Immortal Song', and it's also the first time the two of us are performing like this together, so we're a little nervous. We'll do our best."

Despite their charismatic performance, the T-ara duo lost to Ulala Session, and Jo Jang Hyuk took first.
