Unlucky earthling Jinwoon has the worst luck ever. At work he is being terrorised by his boss. He has no love life and his 'family' life is a pain. His life sadly ends before he can change his ill-fate destiny.

Sung Hoon is the soon to be king of the Kingdom Namgyeong. He was raised by his single father in another kingdom. After his father's death he is brought to Namgyeong. 

After his death, Jinwoon transmigrates to an alternate universe where a mysterious being tells him to find the most powerful person on the planet. 

While Sung Hoon is told that Jinwoon is the only one who can help him save his planet. 
  
Trying to save the planet, Jinwoon (re)discovers things from his past and his new future.

How far do Jinwoon and Sung Hoon need to go to save their (new) world?

VERY VERY SLOW READ.

Tough Bride.

"Have all spaceships move to the other side of the planet and cut off all the systems until they get our signal. Have the Wehikore and Howa reached the randevu site?" Sung Hoon was delegating through his com device. They were getting ready for the invasion.

He looked at the countdown screen in front of him with a frown on his face. Three days ago Seo Ho had sent a message to Sung Hoon that the Crijker's were on route. Jinwoon and Sung Hoon had rushed to Seo Ho location.

They had discovered that he and Min Hoon had reconstructed a cave into a space observatory. The cave was located in the large mountain of Pahodu. Sung Hoon had looked around in amazement. "When and how did you guys do this?"

Min Hoon gave him a toothy smile. We started the day after we found the birthing cave. That's how we discovered when the Crijker's were coming." Sung Hoon gave an impressed nod. "You've done well." He glanced around again before remembering why they had come.

All Hands, Incoming!
