High school student Saito Houjo never imagined his life would take such a surprising turn—he's now married to his classmate and fiercest rival, Akane Sakuramori. The two have always been at odds, constantly competing and clashing over everything. But despite their endless bickering, their unexpected newlywed life is about to kick off with plenty of awkward moments, fiery arguments, and maybe even a few sparks of something more. Adapted from the popular Japanese romantic comedy light novel series by Seiju Amano, with charming illustrations by Nanami Narumi, this anime promises a whirlwind of laughter, tension, and heartwarming surprises.
