Usotsuki ni Chikai no Kiss

Seira can't forget her first love of 10 years. In order to refuse his confession, he inadvertently lies and says, ``I want to get married, but I don't want to fall in love.'' Just then, her first love, Chitose, appears and proposes to her, saying, "Will you marry me?" Chitose is tired of being courted by girls, so if she marries someone who doesn't like her, her troubles will go away. Then, he proposed marriage to Seira, with whom he had the same interests. What is the future of “contract marriage” that starts with a lie?
