In the last episode of the music project 'Good Day' led by G-Dragon, the recording studio features 2NE1’s CL recording for the group song. CL is initially seen in the studio with Kwanghee, eager to interview her. She expresses her desire to sing instead of rap and invites Kwanghee to direct her test recording, seeking candid feedback. Subsequently, TV personalities Hong Jin Kyung, Jung Hyung Don, Defconn, and Kian84 join them. CL happily greets Hyung Don, informing him about her test recording. Hyung Don humorously takes on a "musical artist" persona and offers to critique her singing. He asks CL to sing a line, pointing out areas for improvement such as pronunciation and emotion matching the lyrics, demonstrating the importance of vibrato in a comical way. CL appreciates Hyung Don's wit, understanding why G-Dragon admires him. Their bond goes back to a past incident where Hyung Don humorously criticized G-Dragon's fashion sense, showcasing the beginnings of their beloved bromance. The final ensemble song will be a remake of the classics “Telepathy” and “By the Moonlit Window” by Dosi Brothers, featuring an array of artists from various backgrounds and rearranged by G-Dragon.
