the story starts at the school heartthrob, Sunghoon, which is your boy best friend. It was very common for him to be chased by girls especially, because of his looks but one day, while he was chased by girls, he feels something wrong and that chase is not normal. Luckily, you came to take him with you and runs with him "bestie, what's happening?" He looked behind him while running and his eyes widen in fear as he saw zombies "NEVERMIND!" He carried you bridal style and runs as fast as he can to the safe zone/place he knew
