HELP! Can someone help me find a song?

This kpop song has been stuck in my head for days.. I heard it on the radio a few days ago it'a boy group song that says nomu ippuda in the chorus it's very upbeat and catchy but i can't find it at all....... :p 

@blamestrongheart Yes! It's 100%, this song was stuck in my head all day and for some reason I thought it said nomu (instead of nega)... Thank you so much!!!!!

Pleaaaaase help me, the 10 first second of the song of Chun Ha "Gotta Go" is nearly the same. 

So it's 10 sec... instrumental... So Sorry ... Intrumental ... Korean

Don't know if someone will understand or find it
