Davichi said on the episode, "We are very happy these days. We were worried that people forgot about Davichi's sound."�

The duo also expressed their gratitude in finally getting a fandom, 'Davichi Code,' for the first time since their debut. The girls also revealed that the fandom name was a spin-off of the novel, 'Da Vinci Code.'

While talking about their fandom's chant, Davichi revealed that their fans would chant, "We trust Davichi to listen." However, Davichi asked their fans politely to not shout such things when the duo are singing ballad songs and revealed that they had once missed their cue from laughing.

When asked about plans on releasing a solo, Lee Hae Ri said, "I am preparing a solo within this year, but there are people who want Davichi's Lee Hae Ri and I do want to satisfy their needs. Then again, I feel as though that a solo release would be good to show. I'm still thinking about it."�

Kang Min Kyung then said, "If Lee Hae Ri does it first, the response is good, and I think it is something to attempt, then I would work for [a solo]. I have no plans right now."

Meanwhile, Davichi opened up the show with their OST "It's Okay, That's Love" from the popular drama, 'It's Okay, That's Love.'�
