I’m The Ex-Girlfriend of a Soldier

I’d been reincarnated as the heroine of a predictable third-rate harem novel. I decided to live as the heroine and enjoy my comfortable life with the hero… but what kind of romance is this?! Having a soldier for a boyfriend, there was a constant stream of women surrounding him… and all kinds of incidents occurred. So now I was trying my best to live a normal life. I broke up with my boyfriend and married a man I’d met during a blind date but… What? My husband is the demon king?
“Ha, what do you have your guard up for? Are you scared that I’m going to do something to you? I can see that you’re scared.”
“Why would I be scared?”
“What?”
“What would you be able to do to me? Don’t flatter yourself, I’m just uncomfortable.”
“I want you to be mine, but that seems to be impossible.”
…. No matter how much I think about this, everything seems to be wrong.
