On February 1, BoA uploaded two selfies of her and TVXQ member Yunho backstage at Mnet’s “M!Countdown.”

She wrote, “To be honest~ yesterday at the ‘M!Countdown’ pre-recording, my loyal friend came to cheer for me~ Yunho why are you so cool?~ I was so touched. Thank you my friend~.”

Yunho and BoA have been friends and artists at SM Entertainment together for a long time. They have talked about their friendship on various shows and interviews, and she recently named him as one of the SM artists she could imagine herself in a project group with.

BoA released her comeback track “NEGA DOLA” on January 31 and performed it for the first time on “M!Countdown” on February 1. Watch her performance here!
