First of all.
The characters actions/feelings are exaggerated by 10x's the normal.
1. One character will always say something random in one of the most dangerous moments instead of following the groups instructions or running away, then get killed or kidnapped
2. If the characters know each other, but are not that cool with each other, they won't for the life of them say what they plan on doing even if it ends up killing one of them.
3. Even if it's been 1 day on the island, all girls will lose their integrity for the smallest of items and strip or fuck a supposed antagonist in the group
4. Killing a native that doesn't even look human will make a person in the group contemplate "I just killed a human"
5. Any character will randomly spout some random bullshit in front of the natives at any time, KNOWING they will get beat up and that they have no power to stop the natives and help someone in their group.
6. The smart nerd guy has a savior complex and is willing to put everything at risk unless the blonde USMR girl explains why he shouldn't, yet he still argues
tbh, if it weren't for obvious reasons, I'd think the characters were just fooling around and having fun.
