KGC's manga / #System(1)

I loved the plot, spoilers below tho. . . . . . . . . . . . . though kinda annoying that countless generations of in-laws didn't reveal or give their new daughter-in-laws a heads-up. Also, the system getting basically pissed at the end because she was trying to get rid of it so It just decided to try and off her so the other dude would remarry and carry on the bloodline with somebody more stupid. System was so cool ngl a bit of a bastard but also really cool I loved the fact the system was kinda aggressive and selfish, its rare to find such a plot!! I'd love to see more selfish systems ;-;!
