Johrel went crazy?
One day, when I arrived at the hostel,
I saw Johrel was smashing a chair into tiny pieces.

What I thought were as follows↓
Some scampish guests made you get angry last night?
or
He was sick and tired of Naoto's pranks?
or
He's had about enough of Tomo's unreasonable demands?
I hesitated to ask what happend to him but realized he was smiling:)
Hmmm, he's just doing it to throw it away:P
Don't worry, Naoto&Tomo. He is very mild person♪
