I'm Getting Married to a Girl I Hate in My Class - S01

There is only one person high school student Saito Houjou truly cannot stand: his short-tempered classmate, Akane Sakuramori. The two have never gotten along, and their opposite views and personalities only lead to constant fighting. But everything changes when Saito's grandfather and Akane's grandmother set up a sudden meeting and insist the two get married. Walking down the aisle is the last thing Saito and Akane want, but they are quickly forced into accepting the ridiculous plan and soon move into a shared house as husband and wife. Even though Saito and Akane despise each other, living together under one roof might just turn their bitter hatred into everlasting love.
