You're talking about TWICE, the K-pop girl group, right? In their song "What is Love?", they explore the question of what love means. Here are some of the lyrics:
"Love, it's what makes the world go round
Love, it's what makes the stars shine bright
Love, it's what makes us come alive
Love, it's what makes everything feel right."
Essentially, TWICE suggests that love is a powerful and essential force in the world, and that it has the ability to bring people joy, happiness, and a sense of purpose. It's a pretty feel-good message, if you ask me!
