Group B2ST's member Yang Yoseob revealed an acorn-like image in a suit.

Today, Yang Yoseob attended Jo Soo Mi's concert held at the Olympic Park in Seoul. He appeared in a neat suit. He looked a bit like an acorn, arousing laughter.

Yang Yoseob sang "Mother" and "Love Person" at the concert, receiving much applause. He had sung it for a program before, so Jo Soo Mi decided to personally invite him to her concert.
