Morimoto is getting bugged by her parents to marry (a guy). Her (female) kouhai suggests she fake her marriage so her parents would stop but they will scrutinize every guy she might choose no matter what. Since there's a new law that allows homosexuals to marry, her kouhai suggests herself; only this kouhai has confessed to her before. What will become of their married life?
