There is a rumor. A man who walk around at night with a mask and ask someone he encounter if they find him beautiful, then he would take off his mask and ask them same question. If the one who answer that question say no, they die. If they doesn't answer, they die. If they say yes, the man leave without killing them.

You didn't believe rumors, you walked outside at night when you saw a man with a black shirt and a really pale skin walking around with a black medical mask covering the lower part of his face.

The man approach you with a blank stare.
