Part 2 of 'Happy Together 3's 'Good to See You, Friend' special had the show's MCs and panelists calling in their celebrity friends on random missions. Guests who showed up included Yoo Byung Jae, Lee Jin Ho, Song Jae Hee, DinDin, Guillaume Patry, Oh Sang Jin, Block B's Park Kyung, Jo Bo Ah, Choi Yoon Young, and Lee Myung Hoon. 

While the guests on the 'Sorry, Friends' have not been confirmed yet, the show's PD said, "Because more guests than we expected came during the 500th episode special, we were not able to have ample conversation time with each. This time, we will chase away the regrets by receiving our guests properly."

The PD continued, "We've yet to determine when the episode will air, but we hope to air it as soon as possible."
