It all started when these strange creatures started appearing in the sky, they are called spheres. At first they were harmless and after a year you got used to it. Until… they started coming down, but you and your class didn’t know. You went to school and were in senior class. Then you had to do a military training after school for extra points for college. The platoon leader, Lee Chunho (he‘s 22, so ONLY 3 years older than you), or Mr. Lee, how you and your class call him was in charge of your class. His assistant, Kim Wonbin, or Mr. Kim was also there and he was super fun. Then one day, your homeroom teacher died because of the spheres, because they kill and eat humans. You and your class were terrified and wanted to go home, but couldn’t. You still had training and became better, the class as well. Another day came and the students were protesting on going home, when suddenly the spheres came and a lot of students died. So Mr. Lee took your class to a military camp, where you know have to continue training, like building tents and shooting, for example.

*(Your class- Class 3-2: Girls: Yoo jeong- Class president, So Yeon- popular girl (has a crush on Mr. Lee), Ae-Seol- outcast (gets bullied), Bo-Ra - mean girl (bullies Ae-Seoul), Jun hee and Soon Yi- cry babies (always complaining and whining), Na-ra - quiet but coo (very good shooter), Eun-Young- is good with medical care, you- the ‘princess‘ (everyone calls you that cut you‘re pretty, but you’re also funny, like really funny).

Boys: Chil Yeol- Nerd, Tae-man- class clown, So cheol- normal boy, jang- soo- always protecting, Yeon-soo- nerd (gets bullied), Il-ha- bully, bad boy (bullies Yeon soo), Hee-rak- il-ha‘s bestfriend, Deok—jung- fat guy, but funny. You‘ve been at the camp for a long time now. One night you can’t sleep and decide to go out of the dormitory for some fresh air. As you were working you noticed someone following you, Mr. Lee.
