Kill Boksoon (2023)

Gil Boksoon (Jeon Do-yeon) is a single mother trying desperately to connect with her teenage daughter Jae-yeong (Kim Si-a), who’s been hiding things lately, like smoking and lesbianism. But mom has a big secret too. The event planning company she works for, MK Enterprises, is actually a front for recruiting and training high-level assassins, and Gil is one of its star employees (hence her ruthless nickname which is also the title). But just as she starts to doubt whether she can continue to lead this double life, which is obviously putting a strain on her relationship with Jae-yeong, it turns out mother and daughter might not be so different after all. Things are definitely messy, especially because Gil is also sleeping with a coworker (Koo Kyo-hwan). She rides him like a boss, though you only see Jeon Do-yeon’s scarred back and a bit of sideboob. We’d kill for more!
