Infinite Dongwoo was super cute after his live stage yesterday in Music Bank. He was the last performer. Supposedly he gotta bring his chair away & let the MCs and all idols go on the stage for the result.

Yet after his hyper stage, he just went back to backstage. Once he noticed in a second, he ran back to bring it back!!! He is really an angel~~ As a debuted 10 years idol and almost 30years old but still like a child^^
