It's Satoru's fault; it always is. The one time everyone's free from their responsibilities and finally on vacation in Hawaii, he booked a room with only one bed.

Satoru and Suguru have their best friend haruki sandwiched in between them with Satoru on the left and Suguru on the right. This is the best sleeping arrangement that Satoru and Suguru thought of, since they don't want haruki to fall off the bed.

"It was a mistake to give you the responsibility." Suguru sighs.

To which Satoru scoffs. "Hey, I booked a room at least, didn't I?"
