I was shocked to see this song on the list as "What Is Love" was only released in 2018!

This song is a lovely, bright song, which is a style of music that the TWICE girls pull off well, causing a lot of fanboys to fall in love. Plus, lots of the cute choreography is easy for us to follow along with.
