I Got a Tycoon System and Let It Go to My Head

[No romance, a mercurial heroine, and a light, easy read.] Ying An was frail and sickly from childhood, and spent her entire life in the hospital. Only after she died did someone tell her that this wasn't how her life was supposed to be. The Supreme God had chosen the wrong person, leaving her bedridden in the hospital her whole life. A review of her life showed that she was supposed to have been incredibly happy and blessed. Instead, she'd never had a single friend, from childhood onward. To make it up to her, the Supreme God sent a sentient Tycoon System to make a pact with her, giving her unlimited money to spend and a golden finger. This was the life she was meant to have. But somehow, things went wrong. Countless skills in the shop await Ying An's unlocking, ready to help her reach the top. But Ying An takes life as it comes, and a bicycle is all she needs. She'll spend money when she should, but if she doesn't have to, she can't be bothered. She has a fortune, yet still jostles among ordinary people, even though she herself is anything but ordinary. Her missions force her to spend money. So she decides to try living like a rich person. Once, she couldn't even get near a handsome man. Now that she's rich, she can actually touch one! How could that not be amazing? She'll keep a low profile when it suits her, but she won't let anyone push her around!
