Class no Daikirai na Joshi to Kekkon suru Koto ni Natta. follows high school student Saito Houjou, who cannot stand his temperamental classmate Akane Sakuramori. The two have never gotten along: their clashing personalities and opposite views turn every exchange into an argument, and neither expects that to change. Then Saito's grandfather and Akane's grandmother abruptly arrange a meeting and insist that the two get married. Neither of them wants to walk down the aisle, but the family pressure leaves little room to refuse, and the pair soon find themselves living together as husband and wife in a shared house. What begins as an absurd arrangement quickly becomes a daily test of pride, patience, and reluctant cooperation. Forced to deal with each other under the same roof, Saito and Akane must navigate awkward routines, constant bickering, and the uncomfortable possibility that the person they despise most may also be the one they come to understand best. As their tense domestic life unfolds, the story tracks whether bitter hostility can slowly give way to trust, warmth, and the kind of love neither of them was looking for.
