What a Flirtatious Little Rascal

Please, Everyone! Stories with a System and Multiple Female Leads

I'm looking for books similar to "Rainy Night: My Yandere Little Sister Begs Me to Take Her In" ("Rainy Night Take-In"). Multiple female leads.

My Good Subjects, My Harem Is Empty.

Any Urban Novels with Lots of Beautiful Women, High-IQ Protagonists, and Wild Ideas?

Looking for books like "Ten Years of Seduction". It’s an incredibly satisfying read, definitely worth checking out!
