How many seasons are there in the TV series "Top Floor"? Was Xiao Min killed by an old genius? Is the stalker a good person or a bad person? Will Lao Zhou get better?

It is said that it is three seasons now, but it is possible to shoot again. The Korean drama "Top Floor" has been updated to the third season, because the plot often reverses, so no one can fully determine these problems before the finale, because the screenwriter is also shooting and writing at the same time, so wait patiently for the day of the ending.
