They flee

Thunder is the oldest of the 7 brothers which means he will be the next CEO of the buisness of their Father. Their mother died after giving birth to their youngest brothers Thorn and Solar. Thunder didn't want to take the position neither did the rest so what did they do? They do something idotic. They flee. They become missing hence they change their apperance from fancy to normal. They liked being normal.

This is the summry BTW
