Inspired by famous movies, including Ghost, The Princess Diaries, and Pulp Fiction, the music video draws on the opening lines of the single -- "Every day in a movie, in a book, or in a drama, I feel love I learn about love/ My heart keeps beating as if it's my own story” -- and depicts the women exploring the question of “What Is Love?” by recreating iconic cinematic scenes: Nayeon undergoes a makeover a la Princess Mia; Jeongyeon and Sana recreate the pottery wheel scene of Ghost; Dahyun sneaks headphones on Mina as in the French film La Boum; Sana and Tzuyu have a dance off as in Pulp Fiction; Momo and Tzuyu imitate La La Land; Tzuyu and Jeongyeon recreate the famous fish tank scene of Romeo + Juliet; Jihyo & Jeongyeon reenact an emotive school scene from the Japanese film Love Letter, Chaeyoung imitates Léon: The Professional, and Dahyun, in blatant product placement, poses as a model for Acuvue Define contacts.
The theatrically inspired scenes are interspersed with several group scenes that feature the members of TWICE at a sleepover watching the movies, and dancing in romantic, tea-length cocktail dresses and ‘90s-inspired outfits, as they perform the question mark-creating dance moves.
What Is Love features five songs aside from the single, one of which, "Stuck," is only available on the physical album. "What Is Love?" was co-written by J.Y. Park, the head of TWICE's label JYP Entertainment, while the effusive "Sweet Talker" features lyrics written by members Jeongyeon and Chaeyoung, and Jihyo penned the verses of the swing-pop "Ho!"
One of the most popular girl groups around, TWICE has dominated the K-pop scene since their since their first single "Like Ooh-Ahh" in 2015, which debuted at No. 6 on the World Digital Song Sales chart. Each of their following songs, including Japanese singles, have charted within the top 10 of that chart, and all of their Korean albums have charted on the World Albums chart.
