Xiaoxing, who was diagnosed with "Ublis syndrome" (in simple terms, she lost the ability to be afraid) did not believe that she had this disease, so she tested herself. Turns out anything scary only amuses her. She has become very "manly" since she stopped being scared. In order to find a brave man to fall in love with, Xiao Xingxin will conduct some tests on the boys after meeting them. In the end, they never meet again, until a timid mushroom-headed boy Danan appears......
