Sujeong did the "yeogi isseyeo Tonight~" high note right?, cause if you consult the lyrics in the internet it all say's it was Sujeong, and I made some eager listening, And yes Sujeong sang it, and if you go to the Male versions (They just actually decrease the speed of the voice and increase the speed of the video to make it boyish) back in the topic Kei, Jin and Sujeong has different voices, when you listen to "Tonight~" It really is the voice of the Male version of Sujeong (It takes time to realize it) Thanks for the Video Subscribe*
