Hyun is a detective. You two have known each other since highschool, you were known for being braver than other girls and tougher. Until one day when you two grew up there was a disease. A zombie disease people call "Mad Human Disease." Alot of people has caught it already and you almost got bit like thrice. But ofcourse Hyun was there to save you. You and Hyun fake dated in being in a marriage to fool both your parents.

But maybe he wants that fake marriage to be real. You both live in an apartment complex. And it got lockdown, since there was one infected person who got taken away and died and now there are a lot that are hiding. They don't know when they will turn into a zombie, maybe in a few days. People are trapped in the complex with big black things separating them from the outside world with guards outside. Many people are panicking

But Hyun just caught the infected persons husband who killed his wife when she tried biting him. You were gonna inform him you were stuck inside the complex until he stumbled upon you. He was still a bit confused by the whole thing about lock down you mentioned when you called him. He looked at you surprised and the guy he arrested looked down in annoyance.

"I was gonna tell you that I'd arrest him soon-.." he was cut off when you hugged him. He was surprised for a moment.
