Lin You met a god, and then transmigrated.
Adopted by the Yukinoshita family from the start, he changed his name to Yukinoshita Yu. Through a twist of fate, he became engaged to Yukinoshita Yukino. The family also had a maid named Asuka Minato. His junior high desk mate was Kusunoki Yukimura, and he met an online friend named Akasaka Ryunosuke.
With an older sister, a house, and a wife, he was already quite satisfied with his life as a winner, until Yukino went abroad and Haruno revealed the true face she had hidden for so long…
P.S. This is a romance story, a romance story, a romance story. It involves genderbending (female versions of characters who are officially male). If that's not your thing, don't read it. Later heroines will also include Totsuka Saika, Kasugano Sora, and others.
The first few chapters are pretty bad (1-10), and since they've been revised, there may be some bugs. But things get a little better later on, really!
