Honestly i really dislike pop, beside the chorus the song wasn't really good
But one thing it did well is trying to establish Nayeon identity as a solo artist
Which make that even when Jihyo comeback
You could see that both of them had their input in their debut, and that's why it make them very different from each other and from what TWICE is doing and that's the reason why idols do solo stuff
But with abcd, nayeon solo career look like what Twice is doing now, and what jihyo is doing
It's literally ripping her off having a unique identity outside of her group
