LE SSERAFIM is bringing new music on September 11 with their second single album "Made My Night," and they've already given fans a head start with an early music video release.

The title track's music video dropped on September 11 at 12 a.m. KST, ahead of the full single album release at 1 p.m. KST that same day. The video is a collaboration with the global game Overwatch, marking a cross-industry partnership for the group.

"Made My Night" is an upbeat track about meeting someone special and living in the moment together. The song captures what LE SSERAFIM described as "a night made special by a shared chemistry."

Leading up to the release, the group has rolled out multiple teaser materials. On August 28, LE SSERAFIM shared the initial teaser "YOU JUST MADE MY NIGHT" alongside pre-order availability. Since then, they've released a highlight medley, track list, concept films including "DIGITAL SYNC" and "CHEMICAL NIGHT," and "TRACK CHECK" videos showcasing both "Made My Night" and another track called "AEIOU." A teaser video titled "THE MMN SHOW" also went out to fans.

Pre-orders began on August 28, with the group promising additional details through their Weverse channel. LE SSERAFIM thanked fans for their support and asked for continued interest in the new single.
