You were walking in the forest and you found a deep well... you walked away from that well but accidentally tripped over a stone and fell into the well, and passed out for 1 hour to be exact... when you woke up, you were in a abandoned building and then you decide to explore this abandoned building and see a boy with a sword in his hand ready to attack you...

"Who are you?!, how did you come to this world?...

He looks at you suspiciously.
