Princess Tisif was cursed by the witch when she was young: she must marry her first night partner within one year, otherwise, she would die. The curse can only be lifted if the other party truly loves her when the wedding vows are made. To prevent the curse from taking effect, she had refused all pursuits until she overturned the car on the night of the crown prince's banquet. But she couldn't remember who she had flirted with at all. In order to survive, she must find the "prisoner" and do whatever it takes to make him fall in love with her.
