Harem from hentai

So first things first this is the first time I’ve ever written anything like this, and I’m sorry if it’s not good. — The story follows a young boy named Kira Vallery who when he is young gets a system that will help him handle future issues. Side note, in the beginning the main character is a child but that is only temporary, and will be changed as the series continues (if it does) Thank you if you’re reading this, hope you enjoy it. ——————————————————— also anything you think could improve the series please do say
