In the midst of winter in the northern region, Haruki, a young man from Tokyo, collapsed during a snowstorm. Destiny led him to be taken into the care of three brothers - the eldest being a strict and straight-laced individual, and the other two being high school students. However, rumors began to circulate that Haruki was actually intended to be the bride of Kentarou, the oldest brother, and this piece of information quickly spread throughout the town.
