Natsuo Fujii is hopelessly in love with his teacher, Hina Tachibana. Trying to move on, he agrees to a mixer. There he meets an odd girl, Rui, who invites him to sneak out. She takes him to her house and asks him to have sex with her. Natsuo, frustrated that his love will not bear fruit anyway, loses his virginity to her. The next day, Natsuo's dad tells him that he wants to remarry and his prospective partner is coming to their house that evening. As the door swings open, Natsuo is taken aback to discover that Tsukiko Tachibana, the woman his father plans to marry, has two daughters: his longtime crush, Hina, and her younger sister, Rui.

Domestic Girlfriend tells the story of Natsuo and his forbidden love towards his first love, who is forced to break up when discovered. In the void left, Natsuo embarks on a new romantic journey with his stepsister, the girl he lost his virginity to. The story delves into the controversial and complex issues of romantic relationships that involve student-teacher dynamics and step-sibling bonds, while also highlighting the themes of youth, family, friendships, learning, growing up, career, happiness, and trust.

• Natsuo Fujii: • Natsuo, a 17-year-old high school student, harbors aspirations of becoming a novelist. However, he guards his creative talents as a well-kept secret, concealed from his friends and classmates. During his lunch breaks, he often retreats to the rooftop to nurture his passion for writing. It's on this rooftop that he crosses paths with Hina Tachibana, a new English teacher at the school. She becomes his source of inspiration for him, and he falls deeply in love with her. However, their relationship is exposed, and Hina is forced to end it. In his desolation, Natsuo discovers solace in his classmate and stepsister, Rui Tachibana. • Hina Tachibana: • Hina is the high school English teacher of Natsuo, who meets her for the first time at the school’s rooftop, a place she frequented to find solace when dealing with her own inner conflicts.

However, Hina also becomes Natsuo’s stepsister after her mother remarries with Natsuo's father. • Rui Tachibana: • Rui is a high school student who eventually develops feelings for Natsuo.

She is infamous for being flirtatious and sexually promiscuous (when asked, she estimates she hooked-up with over 30 boys, including one of Natsuo's friends), aside from her hobby of making weird plush dolls. She befriends Rui, who was warned not to deal with her and later sets her sights on Natsuo. She is from a broken family and attempted suicide once. Despite her appearance, she is revealed to be quite smart as she landed in the Top Ten during school exams. • Miu Ashihara: • Miu is the sole member of the school's Literature Club until the arrival of Natsuo, Rui, and Momo.
