The Hero System Glitched And Now It Pays Me to Love My Assassin Wives

I woke up in the body of the empire's most hated tyrant, on the night his five wives finally agreed to kill him. Lunara, named the Sword Saint. Zelina, the Poison Queen. Calista, the captive Saintess. Miralys, the conquered War Princess. And Saoirse, the girl-genius he never once spoke to. Five women, five very good reasons, one shared plan: my death before dawn. I also woke up with a Hero System, it thinks I'm the chosen hero, and it gave me an SSS-rank reward for smiling at a woman who didn't even look up. But there's a rule. Every time I do something genuinely good for one of these women, the System pays me back. 10x, 100x even 1000x It only works if I actually mean it, and every payout drains something the System guards like a countdown. So the new plan: survive the night, keep the crown, and invest in the five deadliest women in the empire until the returns make me untouchable. — Description from novelcodex.org
