Maybe he was guilty of hurting her, and because they are from opposing kingdoms? 🤔 It's just my guess tho..…
He wanted to protect her bc he is a traitor to his country and not let her have to choose btw him and her duty. Her father had also just died. And though he didn't tell her, he showed her with the sweets
I'm rewatching and I just realised Annan is kind of repeating his Jin An antics. We all saw the candies which is reminiscent of her giving him candy, and the dishes interlude, same as when he was too picky. They are in a thatched house (they stayed in a similar one when they were rebuilding the village), where he'll climb to fix the roof (same as then only he fainted on the ladder), she'll treat his back wounds, just like he treated her then. I read that he'll bring her clothes, like she did, and he'll fall asleep and she'll look at him and vice versa, just like in the beginning. She'll play the qin, I'm sure she'll draw sth, too...Everything is re-happening!
