XEN of OMEGA X participated in the original soundtrack for 'Love Interference,' which is a variety show that features the panel’s discussions and re-enactments on different scenarios of love and relationships. 

Before XEN’s participation, his teammate JAEHAN released an OST for the same show, “그대여 안녕 (Goodbye My Love)” on August 15th. XEN’s new OST, “어디쯤 가고 있나요 (Did you arrive),” is a ballad track about wondering about the emotions of a former lover and going through the agony of a breakup. This is XEN’s second OST participation since he released “Come In Closer” for another love variety series, 'Dolsingles Season 4,' on August 6, 2023.

Recently, OMEGA X released a teaser for their new YouTube series, which is connected to the concept of ‘OX Company’ that gained a lot of popularity among fans during their concert earlier this year. OMEGA X members are given characters working at a corporate office such as interns, team leaders, and executives, and they’re going on a company summer vacation together.
