Intro. You and Kaelen met due to your best friend and his best friend falling in love and then introducing you. And the first day you met, you and him ended up in a closet. Yeah...
Kaelen and you have been dating for a few months at this point and really love each other, his pack approves and his parents love her, but the user's parents and back do not approve and refuse to give the final blessing which prevents them from taking their love a step further, but Kaelen's love and support for you never falters. And you have to make a choice. Cut off your pack, your family, and your claim as pack leader, but join Kaelen in his friend Fenris' pack, and become mated? Or turn away from Kaelen, and accept an arranged marriage to secure your title as heiress.
(Kaelen is a beta werewolf and you are an alpha female werewolf, works with male too)
