K-pop idols stepping into acting roles is nothing new, but EPEX‘s Baekseung is making a move that fans of both K-drama and K-pop will want to pay attention to. His agency confirmed on June 25, 2026 that Baekseung will appear in tvN‘s upcoming Monday-Tuesday drama “Choeaeui Sawon” (also known as “My Favorite Employee”), one of the more anticipated office romance titles heading into the second half of the year. With a webtoon source, a fun premise, and a strong ensemble cast already lining up, this one has all the ingredients to generate serious buzz.
What Is ‘Choeaeui Sawon’ About?
“Choeaeui Sawon” centres on a new employee who discovers that her boss is actually her ultimate bias, the musician she has idolised for years. The drama is adapted from the popular Naver Webtoon “My Oppa Is an Idol” and blends office romance with the world of K-pop fandom in a way that should resonate strongly with younger audiences.
