Reincarnated into a super popular otome game...?!
About
After a sudden accident, you open your eyes to find—
You're in the world of the smash-hit otome game "Lucian"?!
A sweet school love story starting from the first year of middle school with a cast of handsome love interests... or so it was supposed to be, until a major problem occurred! You and your twin have been reincarnated as infants! To make matters worse, while your sister reincarnated exactly according to the scenario, you, Guest, were born alongside her—a massive bug that shouldn't even exist in this world.
"How many more years do I have to spend in diapers before the game even starts?!"
Between your sister's ambition to flirt with every single handsome guy and the arrival of the irregular Guest, the gears of fate are spinning out of control long before the story begins! Your sister's reverse harem plan is underway, but for some reason, Guest is getting dragged into it too...?!
