Closer to the Hunter(boyxboy)

Terrance and his family have never been normal although they seem like an ordinary family from the outside, what nobody knows is every generation has its youth and they are dragons who can transform at their own will. He has grown up in the shadow of hunters, because they hide their true identities to protect their families from the hunters before every one of them are dead.
There's another family that trains their children to hunt down dragons and their job is to eradicate every single one, Danny has been born into this family and was trained since he was 8 years old to kill dragons and he had excepted that this was the course given to him and he must follow it through and kill every dragon on this planet.
Terrance has been going to school for the past four years to get control over him, while Danny had just been going to have something normal in his life, but they were both taught at home and were doing excellent in school.
But fate had decided to change their course because Terrance and Danny are bound together by fate and nothing can change that although their parents taught them to destroy each other something else happened that not even they could explain.
This is over a thousand years of tradition was it worth it, to throw it away because of love, love that these to friends have together and want together?
What would you do when your best friend turns out to be your mortal enemy?
Would you fight for the love or sub come to the tradition that is in every family and will their parents accept each other and their relationship or destroy their own?
