My Girlfriend Wants Me to Share My Harem? GWSH

I am Steve.
And there is something strange about the setting of the world I have reincarnated. Wait is that my girlfriend ?! And what the hell is she doing! I have to do something about this.
My heart and brain in unison: "STOP HER!!!!"
My lower body: "Can I join in?"
The maid on the book cover: "Don't look at me, I have no idea how things turned out like this"
Me: "Is all of this happening because I reincarnated without being hit by a truck?"

If you want to know how I got in this mess, you got to tag along with me in this comic story.
