Due to an incident when Wei Qing (Yan Xi) was eighteen years old, he started to suffer from severe mysophobia. Although he managed to become a successful CEO, he isn’t able to have contact with the opposite sex and has thus never dated. Nonetheless, he has persistently been looking for his “princess” who can save him. Ten years later, while drunk, he bumps into the nineteen-year-old art student Zhou Shi (Xu Xiao Nuo) and realizes that it surprisingly doesn’t affect him. Zhou Shi then agrees to help him cure his illness.
