You can tell she's drained. Even though she knows the future from the book, with everything she experienced, she would be really drain of affection and other emotions.
I was annoyed how she ended up at the center surrounded by handsome and brusque knights. Guess it was to save them. But was to corny or I guess "greasy" as koreans say
She never asked why he wanted her and he never told her. Don't show any emotions because it's weakness. I hope she gets over this feeling of being unloved soon. He proposed he should have said why, the girl got insecure and spouted hurtful words.
If I were her I would've pulled out his hair and forget about the contract. It's annoying, I wish to know everything will be good for her but this is totally grinding on my nerves. The prankster should've made the contract with her for her to suffer.
I doubt it is their so called customs. Man, she will be even more traumatized in the tribe. A stranger became the bride of the most desired man in the tribe. Or I bet he has a harem already.
