Recently, J.Y. Park gave the first letters of the two singers featured in "Fever." The initials of their names begin with "S" and "B." He even gave more details about the singers. He said, "S" is his favorite rapper and "B" is a great young female singer and lyricist. "I also asked her to rap even if she's not a rapper", he added. The singer shared that he was introduced to "B" by ITZY's Yeji. 

On November 20, J.Y Park shared on his official SNS a short clip that showed a thermometer with three lines labeled "LIKE," "LOVE," and "FEVER." It also said the entire name of the artists "Superbee" and "BIBI," with a caption that said "The featured artists are Superbee and BIBI.
