Jung Hae-in and Ha-young promote new rom-com 'This Damn Love' as drama premieres

이런 엿같은 사랑 (This Damn Love) launched its first episode on August 7, 2026. That same evening, its two leads—Jung Hae-in and Ha-young—sat down on KBS2 variety show 옥탑방의 문제아들 to talk fitness routines, food philosophy, and king crab dinners.

The drama follows a prosecutor who loses his memory and a boxing coach who claims to be his boyfriend. Jung Hae-in plays the boxing coach.

Born in 1988, Jung Hae-in walked through his fitness regimen: two hours at the gym, four days a week, no exceptions. His diet philosophy is blunt. "If you eat hamburger, you become hamburger. If you eat french fries, you become french fries." He controls the order in which he eats foods and drinks a lot of water to deal with hangovers.

Variety show nerves got to him too. "I ate kimbap at the shop today but got so nervous I had indigestion and even took medicine," he said. (Relatable.)

Off-set, Jung Hae-in treated the entire cast and crew to a king crab sashimi dinner during filming near Yeongdeok. He arranged for staff who weren't on the shooting schedule that day to travel down from Seoul just to join the meal. He also gives clothing gifts to actors and staff on every project he works on. The biggest gift he's given his parents: a car.

Ha-young, whose recent projects have been performing well, said she's been feeling the momentum. "I feel it just from reading comments, and my family seems to love me more, so I'm grateful," she said.
