Le Sserafim has added another 100 million-view music video.

Le Sserafim surpassed 100 million views on YouTube at around 3 a.m. on the 28th with the music video for “Smart,” a song from his third mini album.

The video reached the 100 million-view mark just five months after its release. It was a realization of the overwhelming support from fans around the world.

Le Sserafim now has a total of five 100 million-view music videos. They are “Smart,” “Fearless,” “Antifragile,” “Unforgiven,” and “Eve, Psyche, and the Bluebeard's Wife”.

“Smart” was written by member Heo Yoonjin. The song is about the aspiration to become a winner in this world by being smart enough to recognize heat.

It features a groovy melody. Lyrics such as 'If things go according to plan / I'm a child who will become a butterfly' added to the song's appeal.

The music video was also a big hit. It depicts a group of students standing in a line, watching Le Sserafim expressionlessly, and eventually dancing together and enjoying their freedom.

Meanwhile, Le Sserafim will be making a comeback with their fourth mini album, “CRAZY,” on March 30 at 1pm. The title track of the album expresses the thrill of meeting someone who drives you crazy.
