Well as someone who read the fan translation, nope. There is a novel spin off with him and I believe the blond bodyguard Seph
Those two are main characters of the spin off novels, but in two different ones.
The firefighter's story is about him and keith's blond alpha friend you see at the beginning. There is something special about their second gender iirc.
Does anyone know if we will get some more of the hot red haired firefighter? Any side story including him?
