Young Masters never care about how others feel. Fang Fan, finding that the woman was annoying him, kicked her out of the room without a second thought. Call him heartless, call him ungrateful, whatever—this was his code of conduct. He didn't feel he was in the wrong; if someone made him unhappy, they shouldn't stay around. Out of sight, out of mind!
After kicking her out, he poured himself a glass of water, still in a fairly good mood—after all, the woman had cried miserably before leaving. Whether it was an act or genuine remorse, she was truly regretful. For a woman like her, snagging a young, wealthy, slightly handsome benefactor wasn't easy.
The goal was to make her regret it!
The more regret the woman felt, the happier Young Master Fang was.
Not that he was twisted or anything, but in his eyes, she had betrayed his affection. He had been planning to give her what she wanted eventually, but she didn't trust him and disappointed him. Making her regret was only fair!
