In Feel the POP, there are certain lines that are wrong (Lyric Video Creator's Fault). I'll just list it all down. For the Pre-Chorus, it's Ricky then Hanbin (they're harmonizing with themselves in their parts). Gunwook is the one doing the adlibs in the first Chorus. The "i do care" and "everyday" line is Matthew's adlibs/lines. In the second prechorus, it's Yujin then Taerae (they're still harmonizing with themselves not with each other. In the second chorus, Yujin is the one doing the adlibs. In the final chorus, Hao's doing the first adlib, then Matthew does the adlib towards the outro.
