Han Ji-min, Park Sung-hoon, Jung Hye-sung Star in New K-Drama

JTBC's Saturday-Sunday drama 'The Efficient Romance of Single Men and Women' will depict an unexpected encounter between two couples: Lee Eui-young (played by Han Ji-min) and Song Tae-seop (played by Park Sung-hoon), and Jung Hyun-min (played by Jung Hye-sung) and Im Seung-jun (played by Joo Yeon-woo) in its 10th episode.

The two couples have been following storylines that are polar opposites, from the beginning of their relationships to their dating styles. Lee Eui-young and Song Tae-seop met on a blind date, took a long time to get to know each other, and then developed into a couple. In contrast, Jung Hyun-min and Im Seung-jun met through a used goods trading app, their relationship ignited from their first meeting, and they immediately started dating.

These two couples, who have walked such different paths, will have an unexpected encounter when Lee Eui-young and Jung Hyun-min, who are on a business trip for on-site inspections of a livestock farm, call their respective partners after work.

The released photos offer a glimpse into the distinctly different atmospheres of the two couples. Lee Eui-young and Song Tae-seop are seen holding hands and strolling along the beach on their first trip, sharing their excitement. Meanwhile, Jung Hyun-min and Im Seung-jun display their uninhibited dating style with bold physical contact and deep affection for each other.

At the subsequent meal, the combination of Lee Eui-young and Song Tae-seop in neat date attire, and Jung Hyun-min and Im Seung-jun in cute couple hoodies, hints at different couple chemistry and sparks curiosity about the meeting of the four individuals.
