While B2ST has been praised for their refusal to wear kimonos at a recent fashion show in Japan, member Dongwoon's father has garnered attention after revealing his opposing opinion. Earlier this week, B2ST walked the runway in Yumi Katsura's fashion show in Tokyo, Japan. When they were asked to wear kimonos, they requested that they not wear them, saying, "Please consider the feelings of Korea." Therefore, their request was accepted. Korean netizens who heard of this news complimented B2ST, however, Dongwoon's father, Son Il Rak, a professor of hotel management at Cheongju University, expressed his opinion on the matter through his minihompy under a post titled, "B2ST and kimono". Professor Son posted,

"Since B2ST was scheduled to participate in the fashion show, the problem regarding the kimonos should have been addressed by both parties prior to the event.  How would it have worked out if the hosts considered the anti-Japanese sentiment, which has arose due to the issues surrounding Dokdo Island, and refrained from requesting the use of kimonos? At the same time, I don't think it is advisable for our nation's fans to be ignorantly appaulding B2ST for refusing to wear kimonos. What would you have done if a Japanese celebrity strongly appealed against wearing a hanbok during a fashion show held in Korea? Strictly speaking, doesn't the wearing of traditional costumes have nothing to do with the problem with Dokdo or other such matters? Honestly, are they not problems that should be thought of separately? It is proper to believe that B2ST should have firmly refused to wear kimonos, but if you look at it from a broader perspective, it is also proper for B2ST to have worn the kimonos."
