He is not so cringy in the novel, just convincing, confident and devoted (sure, a tad obsessive of her) and has a large sex drive..... and while she is reluctant to marry anyone - she is drawn to him and does hold some attraction for him due to their night together.
She doesn't get as pissed as I would expect, partially cuz she's been marked, the more time she spends with him the more OK she gets.
In their day and age, marriage is what you "do". She wanted to marry for love. Luckily for the reader, she falls pretty fast.
But while she has a relationship with him, she is still very independent of him in her own way, has some secrets she keeps from him and tries to do what she wants within reason. I like her character
