Season 1
Fuutarou Uesugi is an ace high school student whose standoffish personality and reclusive nature have left him friendless, and his father is debt-ridden, forcing his family to scrape by.
One day during his lunch break, Uesugi argues with a female transfer student who has claimed "his seat," leading both of them to dislike each other. That same day, he is presented with a golden opportunity to clear his family's debt: a private tutoring gig for a wealthy family's daughter. He accepts the proposal, but is horrified to discover that the client is the same girl he confronted earlier!
After unsuccessfully trying to get back on her good side, Uesugi finds out that his problems don't end there since he must also tutor her sisters who, despite the very real threat of flunking, want nothing to do with a tutor. However, his family's livelihood is on the line so Uesugi pushes on, adamant in his resolve to rid the sisters of their detest for studying and successfully lead them to graduation.
