Sealing promises with deep kisses

Before he was sent to the next world, Chunhee asked the Plot God a favor.

"I want to be reborn." 

The Plot God was amused and asked him, "Why?" 

"I want to live... but I also want to save him," Chunhee replied. 

During their fiifth life, Yujin took his life because of the pressure that came from his family and the society. In their sixth life, Chunhee took his own life after being betrayed by Yujin. 

It was safe to say that the world and storylines were getting worse and worse. When Chunhee was sucked into the portal and felt his consciousness back he knew would only exist for a second, he didn't waste time and directly asked the Plot God―the only entity who knew everyone and everything―for his help.

To finally do something to stop his and Yujin's cycle. 

The Plot God was the person in control of basically everything except for one thing―fate.
