"You'd better go home if you don't get enough sleep, Dera," said one of Zen's employees, when Zen was standing and talking to one of his employees too, he heard it.
"I'm fine. Too bad if I have to go home," Dera replied weakly.
"Besides, what have you been doing all night, until you don't get enough sleep? Later during recess, just sleep for a bit."
"I was waiting for someone, but he didn't come."
"A guy? Duh, just throw him into the sea if a guy like that doesn't want to meet you."
Hearing that, Zen cleared his throat. The two of them were a little surprised because their conversation sounded clear to Zen's ears, maybe even to the ears of the other employees. Dera herself did not think that Zen was there. Because Zen's position is behind them.
"Do the right thing, not tell stories outside your job desk," said Zen rebuked.
