Where did you get the yellow hair? What stem?

Yellow hair refers to young unreasonable girls (including joking or contempt). Yellow hair: people with yellow hair are used to refer to men who like to seduce or even rob other people's lovers online. In NTR-themed works, even if there is pure love between the hero and heroine in the plot, the plot always arranges a man to act as a stirring stick, perhaps to stand out. This man and a woman usually have yellow hair, so the word yellow hair is slowly derived. Because playing with stalks magnifies the universality of the above phenomenon, people who are called yellow hair are not necessarily yellow hair, and all male NTR people can be called yellow hair.
