Winter 2019

In their teenage years, few things can hurt people more than the heartaches that come with unrequited love. Such is the case for Natsuo Fujii, who has found himself entranced by his school's ever-cheerful teacher Hina. Deflated by this unreachable desire, Natsuo humors his friends and attends a mixer. There he meets Rui, a girl whose lack of excitement rivals that of himself. After bonding over their mutual awkwardness, Rui takes Natsuo to her house and asks him to have sex with her, hoping that the experience will stop her friends from treating her like a clueless child. With his hopeless feelings towards Hina still on his mind, Natsuo hesitantly agrees.

Equally unfulfilled by their "first times," the two decide to part ways as strangers. However, before he even has a chance to process this experience, Natsuo's father drops a major bombshell: he is getting remarried, and his new wife Tsukiko Tachibana is coming over now to meet Natsuo. As if that was not enough of a shock, her daughters—and, in turn, Natsuo's new sisters—are Hina and Rui Tachibana, the woman he's in love with and the girl with whom he shared his first night. Now, Natsuo must come to terms with the feelings he has for his step-siblings as his eyes open to a darker side of love.

Fuutarou Uesugi is an ace high school student, but leads an otherwise tough life. His 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, with a wage of five times the market price. He accepts the proposal, but is horrified to discover that the client, Itsuki Nakano, is the girl he confronted earlier!

After unsuccessfully trying to get back on Itsuki’s good side, Uesugi finds out that his problems don’t end there: Itsuki is actually a quintuplet, so in addition to her, he must also tutor her sisters—Miku, Yotsuba, Nino, and Ichika—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.
