Conquering Girls in a Dating Sim: Harem Lord System(Dropped)

The world-famous dating sim game "Fantastical Love", was the world's first dating game that had RPG elements in it. Its world consisted of multiple realms and both magic and science went hand in hand there. After waking up from his sleep the one called Leo found himself in the world of this dating sim game, but he was not alone. [The system has chosen you as its host] [Do you want to activate the system: Y/N] 'What the heck is this?' Leo thought when he saw this translucent blue screen appear before his eyes. [It is what it is, haven't you seen a system before in novels or games?] He had seen those things before but he never thought that something like this could happen to him in real life. 'Damn, is this for real?' he thought. [Yes this is real, you are an idiot if you think that you're in a dream or something] [Now, I'm going to ask once again] ['The Harem Lord System' has chosen you as its host] [Do you want to activate the system; Y/N] ******* This is my first time writing a smut no wait, a "different" kind of novel so feel free to provide your suggestions in the comments. I will try to improve as I write more, also, if you want to read a novel with a serious plot then you can check out my other two novels. Update schedule = 1 Chapter/day.
