Xiaofan didn't tell Li Sisi or Feng Feifei where he was going, because he couldn't.
In the end, he only instructed Liu Peng to take care of their everyday protection, and then he left like that.
It's unknown who said it, every parting is just for a faster reunion next time, and it's uncertain if they'll have the chance to meet again.
Xiaofan really hoped not to incur more emotional debts, even though he didn't intend to have excessive contact with Feng Feifei, this woman certainly gave him a novel feeling.
Yet, Xiaofan was quite slow because he didn't realize that besides Feng Feifei, Li Sisi had developed special feelings for him.
"Sisi, stop crying."
"I'm not crying for that bastard, he's so annoying. People tell him not to leave, but he still wants to go. Why do you think he's doing this? A big man, if he wants money, don't I have any? If he wants women, aren't you prettier than those outside, Sister Fei? What's he really after?"
