Grandpa: Dead
Everyone else: Alive
Shun Mi's life sucked. His life could be described as a series of unfortunate events, but he tried to stay positive. He wasn't raised by Ocelots, he had known love from his grandfather, and he had an ever-growing catalog of insults. Things could be worse.
Then, on the first second of Shun's 18th birthday, his grandfather's greatest birthday present opened. A portal to another world and a challenge. A challenge for Shun to make something of himself. To make a difference in both worlds and avoid taking the easy way out.
And, of course, a challenge for Shun to survive doing so.
