Xen, a member of the K-pop boy band Omega X, released a new digital single, “F Killer.” 

He previously released his first solo single, “????? (From Where),” in November 2024, and he has been active as a songwriter and lyricist overall. 

Xen participated in Omega X’s tracks, including “Control” from their first full-length album, “Story Written in Music,” and “Junk Food,” “Hey!,” and “Island” from their third mini album, “Iykyk.” 

With “F Killer,” Xen hopes to demonstrate more of his vocal color, musical ability, and presence as a solo artist to his fans and all listeners.

“I’m very happy to be able to share my song again after the first single, ‘????? (From Where).’ This time, I’m especially excited to present a performance along with the single release. Please give lots of love and support for the new single, ‘F Killer,’” said Xen (real name: Lee Jinwoo).

“F Killer” is an R&B and soul genre track that blends his vocal tone and a realistic message inspired by the Thinking (T) tendency from Myers-Briggs Type Indicator, or MBTI. 

The song defines the process of choosing one’s honest answer rather than meaningless empathy or commonly expected reactions, while expressing the fatigue from relationships with others in a sensible narrative to stimulate the listeners’ interest. 

Omega X recently wrapped up their first European tour and connected with fans in Paris, Frankfurt, Berlin, Warsaw, Vienna (Off Stage Event only), Budapest, Helsinki, and Milan. 

After the release of “F Killer,” Xen held a “Release Memorial” event in Seoul to celebrate the single’s release with his fans.
