He was hungry because no one  gave him food, and the family locked his door, so that he can't go out. He felt tired,and he fell asleep. In the next morning,he found himself as a human, not a disgusting giant insect. He was no longer a giant insect,and he could move like a normal human. He came out his room,and went to meet his family.

So after, they lived a happy life.
