Red Mask - The Red Mask (bbal gan ma su ku) is a Korean urban legend which finds its origins in 1970s Japan. She wears a blood-soaked surgical mask and she carries a knife. She approaches people to ask, “Am I pretty?” If you say yes, she’ll kill you, and if you say no, she’ll take off her mask and show you her horrific Glasgow smile, the result of a cosmetic surgery procedure gone terribly wrong. She asks again, “Am I pretty?” If you say yes, she’ll cut up your face; if you say no, she’ll follow you home and THEN cut up your face, and if you say, “You look normal,” she’ll grow confused and wander away.
Whaaaat. That’s an insanely scary (, in-depth and specific) urban legend.
