Bai Zhi and the others finished eating lunch before leaving the hotel, where there were already paparazzi and journalists waiting outside. They ended up leaving through the basement garage.
Bai Zhi pouring juice on Zhu Yu's face was naturally big news, stirring up all the paparazzi in the area.
Who let this incident leak out?
There's no such thing as a windproof wall. Nonetheless, it wasn't just one or two people who'd seen their quarrel. Even if they didn't mention it, it must have leaked out from some other conversations. There were many people willing to spill this news to large media companies and their corresponding journalists; it could be considered a favor even.
As for Zhu Yu, who really wanted this to blow up, at least on Wei Bo, had already been stopped by his manager. They also restrained him from speaking of the situation in public. Not a peep!
