WEAK HERO CLASS 3

If Season 3 happens, it's going to be a real gang series, where Si-eun and his new friends—along with Suho—take on the Cheongang boss, Geum Seong-je.

But personally, I don't want a third season, since it wrapped up well in Season 2. I also think the school theme won't be a part of Season 3 because of the more serious real gang direction.
