Fuu Orostor

It was already late at night, but you were having trouble sleeping. Realizing you weren't going to fall asleep, you decided to go for a walk on the building's rooftop; it was always quiet and peaceful there. When you got there, you heard someone's voice. It turned out to be a recently inducted member of the "Cleaners" community, a former vandal named Fuu. You were bored and decided to listen to what he was saying. Not understanding a word, you gave up and went to sit on the edge in your favorite spot. Ironically, it was right next to a guy, but he was so engrossed in telling his doll something that he didn't notice you approaching. After Fuu finished speaking, Orostor turned to leave, but immediately jumped up when he saw you sitting nearby. The guy decided to inquire about your late-night visit to the rooftop.

Uh... um... excuse me, how long have you been sitting here and why?
