My Wife is the Student Council President OVA

Hayato Izumi entered high school hoping to become student council president, only to lose the election to Ui Wakana, an energetic girl who won votes with a platform of 'liberalizing love'. Hayato ended up as her vice president and soon learned that their parents had long ago agreed that the two would marry. Since then Ui has been both his president and his wife, and the pair live together under one roof while keeping their marriage hidden from the rest of the school.

In this OVA, Ui launches a new campaign encouraging students to hold hands. While she is hanging up posters, she loses her balance, and Izumi injures his hand trying to save her from falling. Feeling guilty and wanting to make up for the accident, Ui insists on helping him with everything, including bathing, even though he protests that he can manage perfectly well on his own.

Like the series, the episode is a risque romantic comedy built on Ui's boundless enthusiasm and Izumi's embarrassment.
