Activate your ancient setting mind. There's nothing wrong for an adult man (in the ancient Chinese era) marrying a 15 years old girl (which is a marriageable age). Also there's nothing wrong for the ML to keep an eye on the MC practically for 10 years before he got to marry her. Hubby gotta keep future wifey in the palm of his hand or else someone will try to steal her, no?

ML is a sucker for MC. Their scenes together are so adorable (and naughty) if you don't consider their age differences (again, turn on your ancient era mind). The kissing scenes tho /Lord/

Ps. Forget all the antagonist characters, the one that needs a beating is the emperor. The empress deserves more than him ugh somebody kick him for me.

DID NOBODY ELSE THINK IT WAS UNSPEAKABLY CREEPY HE WAS EXCITED FOR HER FIRST PERIOD? 0_0

I really don't understand the main female lead's animosity towards the both of them. I understand taking revenge and feeling bad from your previous life, but her attitude and her actions really felt heavy-handed. I actually felt so bad for both Song Hui and Li Song.

Spoiler for Rebirth of Malicious... Military Lineage:

Compare Song Hui and Li Song to Pei Lang. Yes, Shen Miao hated him and was angry and took her revenge, but like... she did exactly what was reasonable. And he got what he deserved. But there was a limit, and she also eventually stopped hated him and torturing his heart with her animosity.

For example, the FL's half-sister, Wei Zheng, was married off to the cruelest male supporting lead and then arranged to be gang r*ped by him (probably repeatedly, since she only continues to get worse). The thing is, yes, she had joined her mother in disfiguring the FL in the past life, but that was due to her mother's instigations. In this life, she had some small schemes, but-- sigh. Anyway, there's also the girl that liked the ML. She waited for him for years, until she grew so old that it was difficult for her to marry. And because she had tried to chase off the FL with a few harmless words, she was married off to a fickle prince who beat her until she miscarried... LIKE. WTH. In the end, the FL didn't purposefully harm them, it's the author who wanted to provide contrast, I guess? Only, it ended up going all wrong. It just ruins the mood of the novel and makes the FL and ML look cruel. Which, I guess they are. That was never a secret from the beginning. *big sigh* anyway, yeah, that's a thing. It makes the novel really hard to like. No matter how good some parts may be, and how good the style of writing is, as a whole, it's a novel that can only be considered bad.

It's literally said in one chapter that Wurong (some foreign country) women can't be compared to Daliang (?) women because they're taller, and much darker (and the author also has to throw in 'more promiscuous' too for good measure)

And a 23 year old being a constant horn dog for a 14 year old - f*** that, honestly

1. Li Song can bite a fat one, why would anyone like him is beyond me. The previous timeline aside, this timeline he still became a bully in his younger year which is not too bad of a start since he was just a kid, but then even after timeskip he still hold hostility against MC and only change his mind after seeing how pretty she is. Then he try to cover up a mu*der attempt, then he turn into an alcoholic and almost force himself on the MC. Even in the dream world where he met the previous timeline MC, he is still a creep who literally force himself on her this time and his fan still has the gall to call this a nice end.
2. The matter of ML being a lo*icon is also a weird thing to say, I'm not saying he is not being too invasive, but a lo*icon he is not. He became interest in MC for her maturity and intellegent beyond her year. During her entire her childhood he has not make a single s*xual advance to MC and even thinking about finding a good husband for her later which is clearly the sign that he is acting like an overprotective brother at this point in time. Then at some point it turn into love, but he still make no s*xual advance toward her. His first advance toward her was after knowing that she has become an adult. Remember that 20 is call too old to marry in this time period, and 15 is the optimal range for marriage and having children.
3. On the note of the time period, people get uncomfortable with ML and MC age gap romance where MC is too young is also bias. The time period being what it is, child birth is a literal life and death situation and the earlier you have children the better is the norm. Then the matter of s*avery, owner who has literal right over the life and death of servants, father who can take child away from his mother, dog fight, polygamy and so on is also present, but why was so little people who get uncomfortable with that in the review? And where are the people who concern about the little princess and her guard who also has a significant age gap.
4. Then the MC's hate toward almost every other person that do her wrong in the previous timeline. She has every right to hate them, she was kill when she was only 15 and her family has every horrible thing possible done to them. After rebirth she got her revenge and then live her life normally, but still remember her hatred and that is fine, she don't have to change her mind. Why would she has to after Li Song being an ass in his younger year, then after seeing him in the festival he is too busy dazing in her beauty to notice how he was touching her inappropriately.
5. The pinnacle of bias is when they hate how the MC is being a manipulative and evil while knowing that the story is literally a revenge story in the early chapter.
