The Gentlemen’s Alliance + 10

In return for a business loan of 50 million yen, the prestigious Kamiya family gave their daughter Haine away to the Otomiya family. Haine, now an Otomiya, is appointed to the student council of the exclusive Imperial Academy, a private school for the aristocracy. Even though Haine is of proper lineage to be on the council, she finds herself struggling to find her place among the many secrets of its elite members, especially those of the president who holds her heart--Shizumasa Togu, aka "the Emperor."

Haine's family has been reunited, but the estranged Togu family still retains many of its secrets. Shizumasa and Takanari are increasingly at odds with each other as each one tries to win Haine's love. Will the twins ever be able to reconcile when they're both in love with the same girl?
