"Let's make babies!!! :D"
One day, there was a man and a woman. That said man and woman decided to one day make love to one another. The next day after the said pair did such act, the woman announces to the man that she has been made pregnant. The man and woman celebrate, afterwards the man decides on his next steps in life, now that he knows that he will soon be a father and the woman a mother. However, the very next day (yes, indeed the very next day), the man is notified by his friends, to his surprise, that the woman...
... has already given birth and holds a relatively healthy looking baby in her arms. As if to prove this wonderful news, the woman has came with the man's friends from behind them, and looks straight into the man's.... well I don't know, loving (?) eyes. The man was initially very shocked, but has soon later come to the terms, that, contrary to the common sense and previous knowledge he had thought that he knew... that he now strongly believed in his heart, that all of his future children would now be instantly born within a mere 2 days!
...a bunch of summoned people from modern Earth are forcibly summoned and trained to be the weapons/pawns of the fantasy world. Where unlike "MC Hides His Strength", this story starts with the protagonist and other Korean citizens being summoned and shows the protagonist's training in the fantasy world's military.
... even after 100 chapters in, readers still get nothing but grinding and levelling up. Heroine doesn't make any interactions with "sentient" characters, doesn't make any long lasting relationships with any characters whatsoever. (Monsters being excluded from this of course). Reading about the heroine's evolution progress can only go so far without having my mind being bored as heck over.
During the middle of the novel, a new female character that is a close family friend to the heroine is introduced to the story. How she was introduced was that her entire family of nobles were killed by a perp, where she herself was this close to being raped by that same perp, until heroine's family stepped in. Funniest thing is, not even once the story mentioned as to why her family was targeted to be murdered, as the story progressed to focusing on the "Tales of the OP Heroine".
There were many times where the game's other reincarnated characters mentioned right in front of Cardinal, about stuff like capture targets and the character's endings, but the heroine is so~ hella dense to not even realize then and there that there are other fellow reincarnated person right in front of her. I mean seriously, this just went to show how s*upid and low of a character I've come across while reading LNs/WNs. I never played otome games before either when I first started reading this genre, but if Cadinal knows what LNs and "villains" are, I'm pretty sure that a normal sane person would've noticed that overhearing "but Cardinal was supposed to be a villain in the story that was supposed to be X or something!".
... for some reason everyone around her is
accept Cardinal's rather... oddly giddy and "cuteness is life!" personality as the new norm. Thus making all other characters appear to have no coherent opinions and thoughts of their own, thus blindly believing Cardinal's way to be their own way.
