A chemistry graduate student transmigrates to an alternate era. Her parents are both dead, leaving her a huge fortune and a little brother. To keep herself alive and hopefully return to the modern world one day, she decides to complete the System's missions. She not only has to struggle to run a trading company, but also worry about teaching. The male lead doesn't get much page time. This is mainly the heroine's story of striving to succeed, so give it a read if that sounds like your thing.
