After a few months of hiatus from the Korean entertainment scene, rooki group MYNAME finally returned with their brand new single “Hello & Goodbye”.

Following the release of title song’s full music video last week, MYNAME delivered their first comeback performance on this week’s episode of Mnet ‘M! Countdown’.

MYNAME became a hot topic from being produced by singer Hwanhee. The group entered the pop industry in October 2011 with their first title song “Message” and gained recognition with their outstanding looks and high quality power vocals.
