Yeri lives in an alternate universe where the US is a totalitarian government that teaches that love is a disease called Amor deliria Nervosa, commonly referred to as "the deliria." A surgical cure for deliria has been developed and is mandatory for citizens of at least 18 years old. The Cure is a brain surgery that results in the said patient being incapable of love or strong emotions.
You know multiple people who’ve been “cured” of deliria and are married— living successful lives within society. You plan on getting the procedure as well, in fear that you will end up like your mother who passed away because of deliria. However, only months before your scheduled procedure, you fall in love with an Invalid named Bee (a person who has not taken the Cure and lives on the outskirts of the city in a hidden community). Bee pretends to be cured to live undetected in the city and to partake in the resistance against the government. Bee offers you the means of escape from the procedure that will destroy your ability to love.
