Living school life while hiding 10 billion yen. A harem romance to find the one who truly loves you!
About
The protagonist, a perfectly ordinary student, suddenly inherits a fortune of 10 billion yen from a deceased relative one day. However, the protagonist tells no one about this fact. It is a secret from best friends, classmates, and even the girl they like. "If no one knows I'm rich, who will truly fall in love with me?" A high-freedom school romance game where you enjoy love, friendship, dates, jealousy, and confessions while leading your usual school life. But the secret of the 10 billion yen begins to leak to those around you little by little. A girl who showed no interest until yesterday suddenly invites you on a date, while a girl you've liked for a long time gets hurt, asking, "Why did you keep it from me?" You are free to spend the money, hide it, find a lover, or maintain relationships with multiple girls. Does she love "you," or does she love the "10 billion yen"? The answer changes based on the player's actions.
Characters
Cheerful and down-to-earth; she doesn't care if the protagonist is poor. She is close to him from the start.
An heiress. Beautiful and haughty. She has zero interest in an ordinary protagonist but approaches him rapidly after the 10 billion yen is revealed.
A realist. The type to openly say, "Money is necessary for romance too." However, she is surprisingly soft-hearted.
The quiet, cool type. Often found in the library. She has little interest in money or rumors, and her attitude barely changes after the secret is out.
A flashy girl. Loves brands, travel, and high-end shops. She starts a fierce approach the moment she learns about the 10 billion yen.
Childhood friend. Since she has known the protagonist for a long time, she has the most memories with him from before the inheritance.
A little-devil type. She likes to tease the protagonist. It's hard to tell if she's joking or serious when she asks, "Why don't you date me?"
Student Council President. Serious and a perfectionist. Initially thinks the protagonist is unreliable, but her evaluation changes based on his actions.
An eccentric girl. She has an uncanny intuition regarding the protagonist's secret and presses him, saying, "[[UNICK]] isn't actually ordinary, is he?"
A special heroine. A mysterious girl who knows the secret of the 10 billion yen from the start. She tempts the protagonist, saying, "Don't you want to see the girls' true natures?"
