"Three Yuan Girlfriend" tells the story that the hero Guang was originally a sunshine otaku (similar to An Yilun), because he was often laughed at by a female classmate when discussing the interests of the emperor's house such as animation games with friends. At this time, the heroine now acts as a beauty for the hero and praises their friends for their cuteness. Later, when the hero was washing the swimming pool, he was beaten when he saw that Caiye was in trouble and needed help, but this made Caiye like it very much.
