The reason to this is because both songs had the same producer, so that "incoming" sound is basically just a producer tag. It's like the producer's signature.

I think it happens in NCT’s ‘kick it’ as well and EXO’s ‘obsession’

The outro tho💀-

For all those who are wondering why this happened and accusing Nmixx of copying even the sound mentioned here, this is the iconic tag / line of Dem Jointz, who took part in producing these songs. This can also be heard in Nah Nah Nah by Kanye and a couple of NCT songs.

I've noticed it a long ago😂

It also happens in 127’s Sticker

it was in nct 127's kick it too

It’s like “and now the breakdown” in Super Junior “2YA2YAO” and NCT127 “Cherry Bomb”

It's same in kick it by nct

I think it's really historical intro music (kpop), since the song Kick It NCT 127 was released, maybe okey🙂

The outro😂😂

Sticker,kick it ,and obsession

I did notice thisss

Not gonna lie the outro 😭😭

Yes I did. And I think JYP should stop copying SM.

yeah that's because both of the songs are created by sm producers.

Ikr that boys 💀
