I've Been Meaning To Ask...
Aoi Umi Dormitory Common Area
With a blank stare at the ceiling, Hajime lay down on the couch in the common area of the Aoi Umi Dormitory. It was already nighttime, with the cold air whistling through the windows and ruffling his hair. He couldn't sleep, and he didn't want to stay in his room, that's why he opted to stay in the common area. At least there, no one bothered him.
He made sure to tell their group leader that he'd be staying by the common area though, since there's the likelihood of them looking for him when he was, in fact, not missing at all.
