No, it's most likely not. Usually, such shows or stories are made up for entertainment purposes and not drawn from actual happenings. The plot and characters are crafted by the creators' imagination.
Hard to say. Sometimes stories like 'After Party' take inspiration from real life but add a lot of fictional elements to make it more interesting. So, it could go either way.
In my opinion, 'The After Party' isn't a real story. It likely comes from the creative minds of the writers who aimed to bring an exciting and fictional tale to the screen.
