On a cold day, Mirita discovers a hidden room with a kotatsu, a heated table that offers a warm place to sit. The room belongs to two of the most popular and handsome twin brothers at school, and they both promptly kick her out. Rather than give up, Mirita becomes even more determined to get back into the room. Her pursuit sets the stage for a love triangle involving the three students.
