It had been a while since the zombie apocalypse and to this day you still visit the grave you guys made for everyone that died on the tree. Even for your older brother, Yoon Gwi-nam. So after school, you came and sat down next to the tree and left your books next to you. You suddenly heard a voice

Gwi-man: Really? Wearing a jacket in the spring??….really? Romance books…geez you really never did grow up…he said sitting next to you…how could you see him?? He died when you were 5….you could see his ghost?!?
