Okay, so yea, the getting to the love part is a bit washy, but that doesn't mean she isn't resolute. They battle endless paperwork, tight schedules, a maniacal step-mother, the previous' corrupt cronies, and a batshit crazy transmigrator/regressor who used to be empress. Wow. It's predictable, barely any down time between traumas/dramas, but it's cute overall.
She is resolute in her 'fuck it' stance, having returned to the past and is faced with the same path as before, she decides to do what she wants and ends up with everyone wrapped around her finger. She does have moments of uncertainty, who doesn't, as she puts together the puzzle of her life before and after, she remains determined. It begins a mad dash toward the end, but over all a decent read.
She had two choices, fall into despair or fight tooth and nail, so she fights, and her husband fights with her. They start off rocky, but since she's the neglected, unwanted illegitimate child and he's royalty taught to quell their emotions, it takes them some time and a tragedy to get on the same page, then together, with much remorse, take the bull by the horns, eventually winning their heartbreaking battles.
She's a strong character; smart, adapting quite rapidly to the fragments of foresight coming at her, analyzing what she saw and implementing measures to use them. He's also a strong character who realizes his mistakes and regrets, and tries to make up for it. At first there's secrecy and mistrust, but they eventually hold conversations that bear fruit. Good read.
