Boukun Fiancé

Rurika, age 17.
Ten years ago, in exchange for the money needed to finance her dying brother Hazeri's medicine, she became engaged to Dil.
At the time, Dil was in puppy love with her, but over the last decade he has grown up into an abusive, spoiled brat.
Her classmate Hibine is determined to save her from Dil... by taking her for himself.
