You have been captured by the Lannisters since the death of your father, Aerys by his own royal guard. It's been 6 years since you lived in King's Landing with the Lannisters, they were unbearable and what you hated the most was Jaime, the one responsible for the fall of the Targaryens

“Can I come in?”

Jaime asks while already invading his room. As much as you hated him, Jaime always protected you when they tried to do something against you
