I Secretly Develop Myself In The Demon World - Chapter 28 - : Practice Conditions

Harem Dynast is the story of a princess set up in a political marriage with King Lorent, a great conqueror who is often mentioned in the Harem novels.

This novel is also named “The game I got is different from yours” | “Game is different, what to do” | “Every time the target is the big BOSS” | “Why is the BOSS of Horror games always the most handsome?” | “They are running for their lives, I am falling in love”… and so on.

The protagonist is a slave to beautiful faces – he likes good-looking people, can’t say no to a pretty visage, and is filled with thoughts of love. One day he bound with a target-attack system where he can travel from world to world and experience love with the most handsome (key point!) target!

The number of players in each game is not set. The protagonist has only one target – the most handsome one. As he falls in love, he realizes… the other players perhaps, maybe, probably… have Horror? Survival? Escape-type games?
