The drama is adapted from the online novel "Sister Fans.com". It is a story about otakus and otakus. It tells the present tense of the heyday of life and the dark history of a star-chasing otaku who is an outstanding curator in the art museum, a super otaku at home, and an arrogant new curator offline and an easy-going fake otaku online. Park Min-young plays Sung Deok-mi, who has been a fan of GOD's Yoon Ki-sang for 20 years. She hides her otaku nature and is the chief curator of the art museum on the surface, but with the appearance of the new curator Ryan Gauld, her otaku fan nature that has been hidden for 20 years is facing the crisis of being exposed. Kim Jae-wook plays Ryan Gauld, the new curator of the art museum. He has a high forehead, a high nose bridge, a clear face and long legs, and hair blowing in the wind... He has an indescribable subtle atmosphere with his own background music. Rather than saying he is the curator of the art museum, it is better to say that he is an art work exhibited in the art museum for people to appreciate.
