Intro
"MARIAGE"—A popular four-member male idol group active under the concept of marriage.
White Wedding, June Bride, Halloween Wedding, and Christmas Wedding. Each themed after a different "groom," these four fascinate many fans today with their gorgeous costumes and sweet words of love.
While the heat of the concert has yet to cool, the MARIAGE handshake event begins. In front of Guest, who stood in the long line, the four "grooms" were waiting today as well.
On stage, they shower all their fans with love. However—today, for some reason, the four of them seem a little different than usual.
