I'm not sure where the high rating of 8.44 comes from.
While the main idea behind the story isn't necessarily bad, the execution definitely is.
Practically, the 'heroine' tries to save the world by giving birth to the hero. How's she trying to do that? By having the male lead's child.
So far, so good.
But the way she's going about it in the story... Forget it.
She stupidly bottles things up and eventually tries to do it with the male lead while he's asleep.
The communication between them is extremely bad, so bad it's not even funny anymore.
It also gets worse. Much worse.
According to the witch in the beginning, a hero can only be born to soulmates. The heroine DID hear that sentence. Getting a kid alone is completely useless unless the couple builds a relationship of mutual love or at least trust and understanding first.
For plot convenience, though, the heroine completely ignored, misunderstood or even forgot that aspect, I don't know. The problem is that ignoring this important aspect for absolutely no reason kinda renders the whole story stupid.
The heroine should know what do, but she doesn't. Naturally, the couple does eventually get closer and stuff, this story has a clear goal after all, but reading this mess still feels so pointless and frustrating because things should happen very differently tbh.
