[One-on-one romance, childhood sweethearts, mind reading, adored by everyone, modern soul in ancient times, light ensemble cast]
[Note: The heroine isn't really a little kid, so don't judge her thoughts and actions by a child's standards ^ω^]
As a third-year computer science student, Xu Jin can't understand it: she was just bored and opened a novel about a girl adored by everyone. How did she end up reincarnating in ancient times before she was even born?
As someone who knows the whole story in advance, Xu Jin's specialty is silently roasting everything while stuck with the role of a cannon-fodder character.
[Big Brother will fall out of this tree in three minutes and end up with a scar as big as a bowl. Tsk, that must hurt!]
Big Brother: ...I'm not climbing it.
[There's a catch in this military pledge. I remember Dad didn't come home for ten years after accepting it, and died horribly beyond the border.]
Dad: ...I'm not accepting it.
[I remember the enemy army will sneak into the city in less than half a month. Sigh, I can't believe I'll have to watch my family be destroyed at such a young age.]
The Emperor: ...Investigate the entire capital!
As Xu Jin kept roasting everything, she suddenly realized that the entire plot had gone off the rails. Her family was no longer cannon fodder, the nation was growing stronger and stronger, and now even a foreign land had sent a hostage prince.
Gazing at the hostage prince in his revealing black outfit, Xu Jin swallowed.
[Handsome big brother, let me touch you...]
Before she could finish, the crown prince swept her up in his arms.
Crown Prince: What do you do when the girl you raised yourself starts craving men?
Step in yourself, of course!
Looks good, I like this type of stuff
