Synopsis: The heroine, Tokieda Nao, discovers that she has an unexpected fiancé! It seems her father’s company is having difficulty, so in order to save it, he arranged a marriage between Nao and the son of a wealthy man. Unsurprisingly, Nao isn’t exactly happy to hear this news. To make things even more ‘fun’, Nao is attending a new high school. Up to this point, she had only attended all-girl schools. Her new school was an all-boys school until this year, so it is about 95% guys!
