Help, the Dragon Was Captured by the Princess

When I woke up, I traveled through time and became a dragon in another world, only to find that it is too difficult to be a dragon in this world - the ceiling of combat power in this world is all the princesses. Our poor dragons just want to live a peaceful life, but from time to time they are attacked and captured by the princesses. One day I was also captured. When the dragon clan elders panicked and raised ransom to rescue me, I no longer wanted to leave. Just kidding, I live comfortably in the palace, cook for the princess, and she also pays me five insurances and one housing fund. Why do I have to continue to live a life of paying off the dragon loan?
