As mentioned previously, Brian had made a promise that he would try out Hwanhee's ramen hairstyle if they win #1 with "You You You". He told his fans yesterday that he would be boldly carrying out that promise, but asked fans not to laugh! 

Although it was probably hard to keep a straight face for both the singer, Hwanhee, and the fans, the two performed another emotional rendition of their song, which you can check out on the 'Music Bank' article here!

Brian also gave fans a closer look at his hair on Instagram, writing, "We fulfilled our #1 promise^^ keke Wow~ I guess @hwanhee really did look pitiful at the time of our first album keke #FlytotheSky #YouYouYou #hwanhee #brianjoo", bringing laughs to all those who remember Hwanhee's frizzy hairstyle back in the days.
