Last time, it was 2AM's Jinwoon who went to cheer on 8eight, but now it's 2PM's Nichkhun! On the 18th, a video of 8eight and Nichkhun singing each other's song was revealed through GomTV. This video was recorded during 8eight's comeback stage on SBS' Inkigayo on the 16th. In order to support 8eight's comeback stage, Nichkhun had decided to go surprise them in their dressing room. Nichkhun starred in 8eight's The End is Coming music video, and their close relationship showed as they conversated and sang each other's songs. 8eight's Lee Hyun sang their songs I Love You and The End is Coming with Nichkhun. However, during the performance, 8eight's female vocal Joo Hee seemed a little jealous because Nichkhun was singing all of her parts. In response to this video, netizens commented, "It looks like they all got close while filming for the music video and it's nice to see," and "It looks like Lee Hyun likes Nichkhun more than he likes Joo Hee."
