Living in the Same Place, but Not Living Together Jiro Yakuin is a quiet high school student in the class. He was living a life that had nothing to do with his lover. In the midst of this, when the “married couple practice” where they live a pseudo-married life begins, they will form a pair with Sei Watanabe, a beautiful girl gal in the class who is the exact opposite of themselves! It seems that the top performers can exchange pairs, and in order to form a pair with each other's crush, they decided to play a pseudo-couple in earnest.
