[You're a player / Varied tastes / Second person / No substitutions / All male leads are virgins / Western European court]
You're the protagonist, you're the protagonist, you're the protagonist!
You transmigrate into an otome game you never finished. You think you'll have to pursue the male leads, but it turns out they're the ones trying to win you over.
Your green-tea, scheming younger brother who obeys your every command; a knight who seems innocent but is hiding his true intentions; a refined tutor who isn't quite as virtuous as he looks; a rebellious prince who dresses as a woman... and many other special encounters will all fall at your feet.
Good men, men who know how to please you: the more, the merrier!
The System even says that once their affection for you reaches a certain level, you'll need to reward them yourself...
Your charm and wit are a sharp blade that breaks convention. As you sail the sea of love, you explore this world and become a guide to its future.
(All the male leads fall in love with you at first sight. The story takes place in one shared world, with no devoted-love route. Don't read if this is a trigger for you.)
