Sehun wasn't born in any ordinary wolf family. In fact, he was a hybrid. His father used to be in one of the Wolf packs for the Ohs. They were considered being one of the protectors to help prevent hunters from killing other innocent lives of their wolf clan. It was said that once the leader passes away, the ranking as general will be passed down to sehun's father; however, Sehun's father had other plans. following his curiosity instead, his father ended up moving out from the wolf pack and settled in the human world meeting the love of his life who was a beautiful human being. Sehun's father fell in love with a human and ended up having a child after Sehun's father showed his true form to his wife that full moon during his rut. His wife was completely caught off guard from this, but The love they had for each other didn't prevent them from separating with each other. So they ended up taking a risk on having a family of their own in this forbidden love. The first child was Sehun's older brother who is older than him by 3 years. Everything seemed perfect in the life of Sehun's parents, but that was until After Sehun was born. Sehun's father went out to hunt for meat for his lover and kids but at the same time, he didn't realize that would also be his last time in this world after a gunshot was heard piercing over at his body twice as soon as he entered the woods. Luckily one of his former wolf friends was around that time and launched over at the hunter who shot sehun's father. The last words his father said was, "Please watch over my lover... Tell her and the kids that I'm sorry and that I love them." With his final breath, Sehun's father passed away leaving his friend with a duty to notify this to his friend's wife.   

When Sehun's mother heard the news of her lover passing away, she burst into tears causing the newborn baby sehun and his older brother to cry along. It was a tough year for his mother because she had zero experience and knowledge when it comes to taking care of 'wolf children.' Luckily Sehun's father friend insisted on helping out for sehun's mother to help take care of her kids and this lasted for 6 years. Sehun was taught to hide his wolf form, sometimes his wolf-ear would appear causing his mother to panic making him and his older brother wear a hoodie or hat to prevent them from being caught from hunters lurking around in the city. Sehun's older brother was considered to be more of an active wolf while sehun remained as the quiet wolf. When sehun was coming home from Kindergarten, His father's friend picked up Sehun covering him with a hoodie leaving Sehun confused. Sehun could hear gunshots being heard nearby his house with familiar screams that sounded like his mother. Sehun was lost with words unsure what is going on as he looked straight over at the adult wolf who held onto him as he gave a pity and guilty look, "Your mother and brother aren't coming back... your mother told me to take you to the safest place." Tears started to pour down in the 6-year-old eyes as he weeps in the arms of the wolf who watched over him those years when his father wasn't around. From that moment sehun's world change. From living in the human city, Sehun was taken to the island of civilization where wolves live together. He became an orphan after losing his mom, dad, and brother from the hunters; however, Sehun's father's friend, who was the leader of the orphanage ended up watching over Sehun more and treated him more like a parent showing him the life in this island. It took time for Sehun to open up in a  new surrounding especially since he is a kid who always relied on his mother or brother. With that, Sehun change from being a quiet wolf to a more open wolf finally opening up as years go by, becoming friends with the rest of the other orphanage. He started to become a hyung watching over the younger pups as he grew older usually helping the owner of the orphanage when figuring out that was also a doctor. Sehun started to have a goal in life to do the same by becoming a doctor and helping out others. As he worked hard during his school years, he graduated and became a family doctor at the age of 25 years old and is now working at the hospital checking up on patients in all ages making sure they are healthy and during his free time he would volunteer to go to a small clinic and help take care of the pups who are sick and in need for medicine.
