(A fanfiction about a dating sim that's very unfriendly to random characters) A boy from another world, after squeezing a colleague back into the game, is transported to a world he's never experienced before, only heard of, of an otome game. Filled with the pride of China, the boy finds life on the frontier comfortable, until he's 15 and forced by a so-called "madam" to marry a woman over fifty… Leon can only embark on a journey to save himself, incidentally introducing some traditional Chinese crafts to the world. The villains, looking at the sky filled with warships, ask, "So, this is your reason for building warships?" Leon: "I just wanted to avoid marrying a pervert…" PS: This is a completed work; updates are guaranteed, so feel free to follow along.
