We haven't treated you unfairly...
They didn't even bother to refute or criticize Xia Feifei's words.
If that's considered treating people well, then they really wanted to treat Xia Feifei 'well' in her own way, strictly according to her standards!
"You've heard what's been said, will you leave on your own, or shall I have security escort you out?" Sun Chengwan thought, trying to save a bit of face for Xia Feifei.
"No! You can't kick me out, you'll regret this! You'll really regret it!" More than worrying about whether Sun Chengwan would regret it, Xia Feifei was concerned that the bank would seize her property and that she would lose everything she currently had: wealth, power...
If she had known this would be the outcome, Xia Feifei would never have targeted Lin Yibai under any circumstances.
