Sleep, eat, anime, and school---that's where the life of an eighteen-year-old high school student, Roma revolved around until her parents decided to engaged her into an arranged marriage to someone that they haven't met yet in order to save her father from his debts and lawsuit cases that was filed by his creditor.
Accepting the decision was hard to bear for Roma but she can't do anything about it for the meantime. Fortunately, her "fiancé" offered an agreement stating that he will break their engagement and also pay their debts only if she agreed to help him pursue his childhood friend and long-time crush to be his girlfriend and they must keep it a secret between just the two of them.
Would Roma be able to succeed in helping his fiancé to win the heart of his childhood friend? Or it's possible for them to have a different outcome?
