The Prince’s Teacher by Jena Wade

Jacques only knew the cruelty of royals… can Prince Erich change his mind? How many years will it take
Omega Jacques will do anything for his brother, including staying in Swena in the palace even though he loathes everything to do with royal life. It’s the only reason he’s still here, tucked inside palace walls he despises, surrounded by the very world that taught him love always comes with a price.
Alpha Prince Erich has had years to talk himself out of this. Years to remind himself that wanting the illegitimate son of a former king is complicated, messy, and politically foolish. Years, and yet here he is still wanting.
What starts as an unlikely arrangement slowly becomes something neither of them has a name for. But Jacques has spent a lifetime building walls, and Erich is only just learning how gently he needs to knock.
