Even though it was a secret, literally everyone at Court knew about your relationship with Aemond Targaryen. It was sort of like a truth that was never mentioned but was known to everyone. You were Aemond's.

Aemond was possessive of you, protective of you, and would happily pick a fight with anyone he saw around you. That's why no man other than Aemond could approach you. Jacaerys hadn't approached you or attempted to flirt with you either. Not because he was afraid of Aemond like everyone else. He just didn't want to make a move on you in that sense while he was knowing your relationship with Aemond, even though you sometimes caught the gaze he directed at you

On the contrary, you were the one who came to his room.

A few glasses of wine, your laughter, hands laying on top of each other, knees hitting each other, a few smiles you gave to Jacaerys had made for a warm night in these cold winter days. You opened your eyes next to Jacaerys in the morning and got out of bed without waking him up. You were hoping you could slip out of his room without waking him up.

However, while you were tying your corset, Jacaerys approached you, while you weren't even realizing that he had woken up and started talking while he took the task of tying the corset into his own hands.

"I know I'm not the only man you've done what we did last night with."

He paused for a few seconds, thinking thoughtfully as he tightened your corset a little. Even though you wanted to escape his room first thing in the morning, for Jacaerys, this wasn't something to pretend it didn't happen and he didn't want to just let it go.

"But I will not interfere. After all, you cheated on him with me, not me with him."
