The stunning music video teaser for "458," a forthcoming single from K-pop boyband CIX's fifth mini-album "OK Episode 1: OK Not," has been released.

Each boyband member appears in a solo scene in the new teaser for "458," which is filled with images of metal, fire, water, and air. On August 22 at 6 PM KST, the music videos for "458" and "OK Episode 1: OK Not" will both be released.

Four tracks altogether will be included in "OK Episode 1: OK Not," according to a tracklist that was previously posted on CIX's official Twitter account. The album also has the songs "Without You," "Bend the Rules," and "Drown in Luv" in addition to its title track.

The upcoming mini-album is a continuation of the band's ongoing "OK" series, which began with their debut studio album "OK Prologue: Be OK" in 2021. Abby Webster, a contributor to NME, gave the album a four-star rating and stated: "Boasting the group's most cohesive sound to date, this new entry promises even bigger and brighter things on CIX's horizon."

According to a press release, this upcoming instalment of CIX’s "OK" series will explore the pain, desire, patience, and emptiness experienced in love.

CIX also recently wrapped up their 'REBEL’ US tour, which took place across six cities from April to May 2022. The tour also marked their first-ever overseas performances since they debuted in 2019.

In an interview with NME at their Los Angeles show, member Yonghee shared: “I feel very honoured and thankful to know that our songs and K-pop, in general, are dearly loved in a country far away from Korea.”
