idk about the replies - but i was sure i remembered right - u can even go check it out urself - in the 1st chapter when she regains consciousness, she says (page 10) "so i have possessed a character in the novel i was reading..."
so her reaction is weird in the latest update - i would get her falling in love - i.e the love growing for the ML, but as they spend almost no time together, this just felt sudden ┑( ̄Д  ̄)┍

Even if the mind thinks it’s a stranger the body can naturally have the same feelings towards certain people. Like how some people with amnesia tend to shake, tense up, etc around those they dislike or fear. Despite not knowing who that person is, their body instinctively remembers how that person made them feel. So it could be along those lines that she naturally still felt drawn to him and felt affection for him

They had some moments together.
Some people don't need a lot of time to fall for someone.
Hints love at first sight
She adored her son and her husband is very similar in the way he expresses himself.
I think she understands him better thanks to doting on her son.
She sees how dedicated and devoted her husband is with her. He has some serious patience. It's hard to ignore sincerity and seeing someone who genuinely treats you like there whole world.
They slept next to each other for a while, the storyline is more fixated on her as a loving mother so they don't really share their alone time much.
If you reread you can kind of see when her mindset & feelings towards her husband changed.
so how come she's declaring her love to the ML?
i get her wanting to get close to the son, cause she felt sorry for the kid & was trying to make sure he didn't end up evil. but the confession & kiss felt out of place. was she ever in love with the ML? she isn't the really Sheriel - no? ┑( ̄Д  ̄)┍
