The Goddess Rebate System: I’ve Got My Eye on You!

[Not mindless, relatively realistic and true to life, logical, no exaggerated campus-beauty tropes, the protagonist isn't a simp and acts when he should without dragging things out, no pretending to be weak before revealing strength or mindless face-slapping and showing off, the System doesn't take center stage, no absurd powers like enhanced eyesight or superhuman kidneys, satisfying, pure wish fulfillment.]

There are multiple heroines, but they're all sensible. (Anyone who isn't sensible won't be added to the harem. Consider this your warning! The male lead isn't a simp, and there are no so-called campus beauties who act like fools. If you don't believe me, read the novel.)

This isn't really a billionaire fantasy. Money is treated like money, and things follow realistic logic, but it's a parallel world, so don't take it too seriously. (He won't spend tens of millions and still fail to win a girl over.)
