In the end

To everyone hating on any individual, just remember this:

in the end, everyone in the show is going to get more money, more famous , and most probably, they will be chill with each other and stay friends.

Look at Gwan Hee, someone who is almost universally disliked by the public. Even after all that, cast members are still going for his basketball games, hanging out and doing stuff together. If he was such a douche like the show/public made him out to be, I doubt the cast will hang out with him after the show (not like they needed to)

So tbh the only people staying salty and hurt are the haters
