Lee Hongki shares a group photo of FT Island and CNBlue on his twitter account. On August 10, he wrote,

"Fnc familly summer sonic in tokyo!!! Well done!!! What... my pants got ripped and my underwear was shown but it was live kkkk :-) Tomorrow we will brighten up Osaka!!"

In the photo, the cool guys are still wearing their family shirt and obviously sweating from their successful performances.

Indeed, you are going to love these boys of FNC!
