Lee Sunmi was born in LA , California . Her mother is Korean and her father is American . Both are purely borned as werewolves . She have a twin brother who annoyed the hell out of her but she loves them . She lived in LA for 9 years and moved to Japan due to her parent business . Her first experience on shape shifting was when she was 10 . Luckily at that time she was playing hide and seek with her twin brothers in the forest .

When she turn into a wolf , her twin brother instantly changed into their wolf form . If she would describe her first experience she would say it felt like dying but it was momentarily . After staying in Japan for 4 years , her family moves to Korea , her mother origin . At first she doesn't belong to any pack but as she turned 16 , she met the Princess of the wolf clan and became friends . 

Slowly they met with the Alpha and they formed their own pack . At first there were only three in their pack . One by one she met the members of her pack . 

Two years after the pack was formed , she was out of the town to meet her brothers and while hunting with  her brothers , she met her mate's pack which is known as Exo-K . She brought along her mate's pack to meet with her pack . A year after being together , she and Kyungsoo was on their way to visit her brother's when they stumble upon the hunters . They were on their guard but unfortunately the hunters caught them off guard . One of the hunters caught her and Kyungsoo tried to safe her . After releasing her from the hunter , Kyungsoo told her to run away and get help . Even though each of them have their own power , it couldn't help that and she knew that this hunters is even more experienced since they had blocked their core energy from using their own power .

So she did what Kyungsoo asked for and quickly ran to her brothers . By the time she arrives back , Kyungsoo wasn't there nor the hunters . What's left is just a pool of blood and blood stain on trees . She regretted listening to Kyungsoo . She regretted for not helping him and leave him alone . She was in a state of depression for 5 years and her pack was worried about her . Her body slowly becoming thinner , even her brothers couldn't do anything to help her . She was too depressed after the lost of Kyungsoo . She doesn't know what it felt like to lose a mate when she saw other werewolves getting depressed but she now know and she felt like dying . She was slowly dying from the inside . 

5 years after losing Kyungsoo , the teritory to her pack was ambushed by a group of hunters . At first she doesn't do anything and let her pack fight them . She could hear her pack whimpering in pain and some even calling out for her . That was when flashbacks of the past came , she wouldn't want to lose anyone anymore . Not her pack , not her family . And so she did what any other werewolves would did when being threatened . She got out and killed the hunters , mercilessly as she remembered the blood of her mate . Nothing could stop her from killing them , revenge was what she wanted but the hunters that ambushed them wasn't the one who take away her mate . After defeating the hunters , she went to her pack and healed them instantly . She apologizes to them for being late .

After that she had sworn to take revenge on the hunters that had took her mate away . She would often found in other packs territory and in the city . Asking around and searching for the hunters .
