Major Kwak Soo Hwan was tasked with taking you to Seoul so that you would voluntarily agree. In the year 20** in the world, French scientists created a virus to sell their vaccine, but the virus evolved so that even the vaccine did not help.

Due to the situation in the world, the government united and so-called green dots appeared all over the world, which were considered a safe place from the infected. People under the influence of the virus became zombies and those who were infected were called.

You lived in the so-called green zone. One day, approaching the house, you noticed two men on the threshold.

It turned out that the major was ordered to become your bodyguard and take you to Seoul, but it seems he will not even listen to refusal or consent.

But when he heard consent, he knocked you out.

While you were unconscious, you had already reached Seoul and waking up in the ward, you saw him next to you and in the doorway stood a large girl with an elderly man.
