My fave is cute again today!
Otaku culture. Japan. What a magnificent game! I spent every waking moment playing "Serenade of the Falling Night." My favorite character was Lylia, the heroine—a choice practically unheard of in an otome game. She's cute. She's cute. She's so cute! I must have played it too much. Huh...? Wait... my consciousness is... How many days has it been since I slept...? Ah... wait, Lylia... chan... ┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ I reincarnated into the medieval European world of the otome game I played in my previous life, "Serenade of the Falling Night." And of all people, I woke up as the villainess. To make matters worse, my fiancé is the Crown Prince, who is destined to end up with the protagonist in the game. Naturally, in the original story... Villainess → Broken Engagement → Condemnation → Exile from Society It's the absolute worst route. Forget that! I'll pass on the engagement with the Crown Prince myself! Now then! I wonder where my darling Lylia-chan is...???
