Lost Ticket to Heaven

Ki-hyuk, a high school classmate, and Yoon-woo, who have been sexual partners for a long time. He feels extremely depressed about the ambiguous relationship between friends and less than lovers, and Ki-hyuk's attitude of only looking for himself when necessary. Meanwhile, in heaven, the angel 'Jun' is waiting for the day when he can't forget Yoon-woo, who had been kind to him, who was a puppy, even after he died. One day, when Yun-woo's fate written on the list changes to 'Train to Hell', Joon breaks the rules and descends into the human world to change his fate. And unlike Ki-hyuk, he begins to melt Yun-woo's frozen heart with a warm and friendly attack of affection...

“Yoon-woo, I can wait. I will never leave.”
“With him… I can laugh.”
