I ain’t trippin’, she ain’t trippin’
We just chill all day like we on vacation
She my homie and I her homie
And we both know we ain’t leavin’
(Verse 3: Felix)
I ain’t tryin’ to be her dad or her boss or nothing
She just my girl and I’m just her bro and her friend and her homie and her lover and her son and her teammate and her doctor and her lawyer and her everything (Yeah)

We go through ups and downs and we still together (Yeah)
And I ain’t even trippin’, she ain’t even trippin’ (Yeah)
(Outro: NCT DREAM)
Yeah, I got a girl friend (Yeah)
Yeah, I got a girl friend (Yeah)
