Junpei Kousaka is a high school student who dislikes cats due to an allergy. Despite being surrounded by cat lovers, including family members, friends, and crushes, he hates everything related to them. One day while returning home from school, Junpei tries to kick an empty can into the trash but misses. Instead of going to the garbage, the can breaks off the head of a cat deity statue, cursing him with the ability to understand cat speech. To lift the curse, he must do 100 good deeds for cats while keeping his secret from others because anyone who finds out will become more accident-prone and suffer the same fate as him. If he fails to complete this task, he will turn into a cat and face certain death due to his allergy.
