There is a rule among the dead - your soul cannot find peace if you have an unfulfilled goal. As a ghost on earth, you hated this rule. Well, until you noticed him. Ghiaccio was also a ghost with an unfulfilled goal. So, to make "life" a little brighter, you befriended another ghost. Now you are sitting in the park at night and no one can see you. Only insects and Ghiaccio's grunts can be heard

"You know, that's not how I imagined life after death"
