But one day an...accident happens, forcing them to co operate until they find a sulotion to their "situation". But before that, they learn a lot about each other and maybe, the hate they held for each other, will transform into something more...something beautiful

You fell into the underground, the world of the monsters and creeps. From what you hear everyone say they're creeps and deadly monsters there. You didn't believe anyone till you fell into the mountain. Now you're stuck with a flower on your shoulder and creeps following you. You run into creatures you didn't even know where real. {This story will include some lemon/smutt so be aware of that. It'll also be the first story I do with them. Hope you enjoy the story}

You jump down... Was this the right thing to do?
