Actually, Bo Yan also had this realization early on.
Originally, he and Xia Siyu were top celebrities, and recently because of "Storm," they've exploded in popularity, and various rumors have drawn even more attention.
Even without these rumors, he and Xia Siyu have long noticed the presence of paparazzi. They act extremely carefully, but even so, there are still paparazzi constantly following them.
In fact, he isn't entirely sure that the people following him are definitely paparazzi. Bo Yan and his team are staying at the most expensive five-star hotel in Shangcheng, with extremely strong security. During this pandemic period, to protect customer safety, even entering the hotel requires security checks.
But security can only guard against bad people, not paparazzi. For photos, paparazzi can lurk in such hotels for a long time, booking quite a few rooms and pretending to be guests, just for the sake of taking pictures.
