I Reincarnated as an Alpha

Kana Matthews died as a human. 
She was ready to meet her maker but instead, she woke up as a little girl with dog ears on top of her head and a wagging tail. She had been reincarnated into a wolf beast! It wasn't easy but she was able to accept her new life in a not-so-modern world as an esteemed noble. She had vowed not to make the same mistakes she did as a human. 
However, when a familiar face claims to be her fated mate, everything gets turned upside down. To make matters worse, the Crown Prince reminds her of a love she rejected in her past life and her knight best friend reminds her of a love that could have been. 
If she's going to live this time without regrets, will she be able to choose among the people who remind her of nothing but the regrets she had in her whole human life? 
Will she be able to keep her promise or will she ruin her new life with the same mistakes that made her death as a human so utterly bitter?
