On November 28th, Super Junior’s Yesung gave vocal lessons to his fellow members, Donghae and Eunhyuk.

He wrote, “This is Singapore .. I’m giving singing lesson for 2 dongsaengs to have a better performance on tomorrow and the day after tomorrow~~ ㅋㅋ”, and attached the above photo.

Although Yesung is trying his best to help his members, Donghae and Eunhyuk show no concern for their teacher and continue doing their own thing with earphones in their ears.

Member Siwon, wanting to take credit for the photo he took, tweeted, “For your information, photo by SIWON. A photo contains a lot of thing~^^“.

Fans commented, “Yesung should credited Siwon for the photo, they are cute,” “Photo by Siwon is funny,” and “EunHae listen to your teacher!”

Meanwhile, Super Junior is currently in Singapore for the 2011 MAMA.
