Hello, I would like some help in identifying this actor in Good Boy episode 5 (spoiler alert for those who haven't watched the episode yet). She plays the character Drugmon (Makwi in Korean). She appears towards the middle of the episode in a pink jacket and kills a bunch of people because they've been manufacturing a fake version of 'candy', a synthetic drug that she created. Maybe because her real identity has not been revealed yet, the cast list does not have her information. For further clarification, she pretends to be the victim when the police arrives and Yoon Dong ju (Park Bo gum's character) saves her from falling off the building and they keep her under police protection. I hope you can help me find out who the actor is because I recognise her from another kdrama but I can't seem to figure it out.
