When South Korea is faced with war threats, it’s president resorts to every measures possible to counter them. And he found them: Children.

The year 2050 was marked as a dark year in the World’s and South Korea’s history as all children inSouth Korea astonishingly died of a viral epidemic - ‘Nox’. And finally in the year 2065, South Korea, with the help of their alliances, proudly announced the temporary cure - a vaccine, for Nox. And it was as good as an answer as finding the cure to the epidemic for the devastated couple who’d lost their child and children, as well as a relief for couples who wanted an addition to their family. With the help of the vaccine, some children survived, while the rest were still infected and perished to the battle against Nox.

Oh Hani, a 17 years old teenager, was one of The Survivors, as deemed by the society. She was thankful for every single day that she had lived - being able to attend high school, being able to make friends, and just being able to breath and being alive. But all her years of happy life could have passed by as a dream when she stumbled upon another teenager who gave her a silent cry for help.

Who was she to deny a helping hand?

But the turnouts of events made her began to doubt everything that had happened and was happening around her. She knew that curiosity kills the cat, but she still let her curiosity wonders, and it led her to meeting new companions, fighting uncountable enemies and maybe, uncovered the concealed truth.
