I remember K-actress Lee Sung Kyung working nonstop with at least a drama a year after her debut and breakout right off the bat in It’s Okay, It’s Love. She did a few memorable stints in second lead territory before her first lead in Weightlifting Fairy Kim Bok Joo in 2016. After that it was lead land permanently but she has been away for over two years now since Romantic Doctor, Teacher Kim 2 in early 2020. If she was a guy I would have thought she was off in military service lol, but all joking aside maybe she intentionally took a breather and coming back with the tvN drama Shooting Star is the project she was waiting for. She plays a PR manager at an entertainment agency and falls for the emotional top star male lead she’s tasked with wrangling.
