World Star Singer Rain appeared at "KBS 2TV Happy Sunday - 1 Night 2 Days" as the morning angel, and ended up being mistreated by the 1 Night 2 Days members, making the audiences and fans laugh.
On the winter break special episode "Northern Kyung Ki Do Tour" of "KBS 2TV Happy Sunday - 1 Night 2 Days" which aired on January 19, 2014, the 1 Night 2 Days members Kim Joo Hyuk, Kim Joon Ho, Cha Tae Hyun, Defconn, Kim Jong Min, and Jung Joon Young saw that singer Rain visited the team as the third morning angel of the season 3 of "KBS 2TV Happy Sunday - 1 Night 2 Days."
1 Night 2 Days members were so disappointed to see Rain as the third morning angel, especially because the two previous morning angels have been HyunA of 4 Minute and Suzy of Girls' Generation. 1 Night 2 Days member Cha Tae Hyun, who is good friends with Rain, said to him, "You knew that this was the third morning angel, did you not? Your come back is important, but did you really have to do this to us?" Cha Tae Hyun also let the audiences know that Rain woke the six members up with a kiss on the cheek, adding, "I was going to kill him."
Rain then said, "I am an angel too," but the 1 Night 2 Days members said, "You are the boyfriend of an angel," referring to Rain's girlfriend, actress Kim Tae Hee.
