Partly the reason why I liked it because the main guy seemed to be more aware of his feelings after that life time. He definitely chased her first all due to her changing "fate" that the Heavens bestowed on her. She was suppose to "chase the husband" and was suppose to "die first", but due to her not wanting the Heavenly Emperor to control her fate, she changed her fate. Also, if you have to asked me who fell for who first, I think the main guy did first. But he was too stubborn to admit his feelings first and so she had to be the one to give in and make him admit it too. The scene where he finally admits his feelings is very adorable and spicy. XD He sure is tsundere and he's definitely not romantic, but his face can't hide his emotions when he's in love. The ending was adorable and I enjoyed the story better than I expected. I was expecting a lot of heart ache due to the "seven unfortunate lifetimes", so I knew what I was getting into.
I liked that the author put more dept into the characters emotions which brought out lots of emotions for the readers to sympathized for both main leads each lifetimes they had died or lived. Also for those that said the female lead is like a monkey, she's really not. I find her character to be interesting because she actually isn't a "docile" female lead that will follow the whims fate has laid on her. I didn't like the 2nd life story as much as the first because of how her brained worked that life time, but that wasn't her fault. The main guy fed her too much forgetfulness soup, so it resulted her to be a bit dumb that life time. Can't blame her for hating her "stupid" version of herself that life time. The main girl does have a brain and knows how to use it, she also admits she's not smart in the love department but that doesn't make her dumb. She realizes her emotions and accepts them too later on in the story.
Although she uses her fist on the male lead, she does it for a reason. The main guy says some really hateful sh*t which makes me want to punch him sometimes too, but he learns and changes in a better way after meeting and spending time with her. His heart also softens and he learns to love because of her. Although he doesn't like admitting that he gets jealous when other men touch or talk to her, he accepts that he does love her eventually causing him to not want to part with her every time she dies. I also like that she's pretty straight forward and doesn't hide behind a bush about herself. She's not a fox in sheep clothing and will tell the main guy straight in his face what she really thinks. Also her questioning the guy right in front of his face asking him if he really likes her makes it even more amusing because she knows she's "thick-skinned" trying to get the main lead to admit he likes her. Although he doesn't sugarcoat it, he does eventually tells her in a funny way that makes me even flabbergasted the way he said it (which happens in a scene where it's done in a special way - the scene I said above about the "spicy" scene). Their relationship is a typical bickering couple, but with these trials you see that there's more too just a bickering couple. She's a sly cunning lady (also stubborn) and he's a stubborn man with a bad tongue, but together they make each other. They learn to love through these trials and with time they have bloomed into a cute couple that can't live without each other that was first formed by their hate for each other. I'm glad they got married in the end. Only sad thing I can say after this story ended was that I wanted to read more sweet moments between the two, but because the ending was satisfying I'm okay with it.

Lives:
1-2 Only one of them remembers at a time and is required to protect and grudgingly raises the other while they're vulnerable. They begin to develop feelings but are mostly in denial.
3 A gimmicky life as a tiger and boar - sets the scene for the antagonist.
4 Both remember but their genders are switched.
5-6 Both remember and are sent to take down the antagonist of the series. Male lead's soul is scattered.
7 Similar to the first life, female lead remembers and needs to protect and raise the male lead so that he can become an immortal again.

The male lead develops strong feelings for her over the first life, having fallen for the real her and gradually becomes less petty. While the female lead has slow character growth until the last life, having been protected by the male lead.
