Tipping and cashback rewards, all the male idols are vying to make me the number one on their donati

Shen Zhaoyi is bound to a system—as long as she spends money on men, she will receive an irregular amount of cashback.
But there's a bizarre rule: the proportions must be calculated based on appearance.
Thus, she was forced to start a behind-the-scenes experiment of "exquisite fishkeeping and raising exquisite fish".
She made a tentative purchase from a race car driver who never showed his face, but he treated her like a minor and taught her how to apply for a refund.
Sending a cigarette to a seemingly aloof and ascetic medical blogger only to receive the comment, "Impulsive spending is not the right thing to do; I suggest you make an appointment with a psychiatrist."
I tipped a voice chat host to help me fall asleep, but unexpectedly the roles were reversed, and I ended up curing the host's insomnia.
……
It was originally a mutual exploitation, with each getting what they needed, but unexpectedly, the fish gradually began to exchange genuine feelings.
"Miss Shen, the tip is enough to buy my lifetime medical consultation rights. Are you sure you don't want it?"
"The trophy belongs to the team, and I belong to you."
"If you need me, I'll always be waiting in the dead of night."
As the plot gradually goes astray, Shen Zhaoyi tries her best to turn the tide, but she also doesn't forget to start a business with a retired idol-type live-streaming e-commerce host, and open a studio with two brothers from the dance area who have a contrasting personality.
As for the stubborn but soft-hearted male escort, well, we'll order him next year!
