Previously we reported that�4minute's�Gayoon�and�B2ST's�Kikwang�will show off their friendship on an upcoming episode of 'Happy Together 3' and the show finally aired on January 1.

Gayoon flustered Kikwang a bit as she revealed the story of how he loves to be called "oppa" (what younger girls say to older boys).

She said, "I first met Kikwang oppa when I was a trainee, but it was awkward because we couldn't establish a ranking. �The company told me to get along with Kikwang oppa like friends because we were born in the same year. �However, Kikwang oppa approached me cautiously and asked me to call him oppa. �

Honestly, Kikwang oppa and my birthdays are only about 40 days apart, but he pretends to be an oppa because he was born early in the year."

She also revealed that whenever Kikwang talked to her, he would refer to himself in 3rd person with "oppa~," making everyone laugh.
