The couple visits the Cube Entertainment recording studio for a duet project, which they work on together with BTOB member Hyunsik.
While ironing out the lyrics, Yook Sungjae excuses himself to use the bathroom but returns with a pair of headphones decorated with a tiara that he puts over Joy’s ears. He then enters the recording booth and sings a live rendition of Han Dong Joon‘s “I Love You” for Joy.
Joy is touched, but the same cannot be said for bandmate Changsub who is looking on. “You’ve got to be kidding me,” he says.
After the song is over, Changsub whispers to the camera, “I don’t think Yook Sungjae is mentally well today.”
