My Wife is the Student Council President

Izumi Hayato launches a bid to become the student council president, but a stunning rival arrives bearing a vow to liberalize love and even flinging condoms into the audience, leaving him defeated and cast as vice president. At the student council meeting, the newly elected president invites herself over to Hayato's home and proclaims that she will become his wife, a consequence of a drunken, decades-old promise between their parents that their children would someday wed. Hayato is firmly against it, while Ui responds with unrestrained enthusiasm and even longs to live with him. Can the reluctant Hayato and the ardent Ui balance their school duties and a secret marriage, or will they ever understand each other's true feelings?
