The MC is not an arrogant type and doesn't carelessly kill people nor let the others died in his presence. He also doesn't treat his woman as a sex object. Even though this is a harem story, some parts of this story will make you tear up and have some funny scenes. Warning! This story has a lot of steamy scenes and playful kinky games that you've never read before. Read by your own risk. Some illustrations and characters images is in my Discord channel. >Cover by commission JustRFL https://justrfl.carrd.co/#commission https://www.patreon.com/nanakawaichan Donate to help me continue writing.
