A Wolf in Billionaire's Clothing
This was free at ARe. It's super short and involves insta-love. There seems to be a time inconsistency, as well. After her first day of work, Miranda is saved by Liam when a man accosts her while she's walking to the subway station. The next day, he lets her go home early. The day after that, he asks her to work late. That night, they discuss the subway incident and refer to it as having happened the previous night. Anyway, it was too quick and she was too accepting of his life situation.
