Self Bondage [School × MS]

"Okay, everyone, be in line and follow me," Yuta said as the line formed and everyone started walking out of class.

Ryuki and Riko shoulder-bumped against each other, but that was okay. They didn't fight about this since Ruby was behind them, glaring at them. If they fought, Ruby was more than happy to give them a beating.

So, Ryuki and Riko honestly followed the line. As they walked out and reached the corridor of the first floor, they saw a steel door that blocked their way.

"Hey? Why is exist is blocked?"

"Is there any button to open this entrance?"

"Are we supposed to break it open?"

"Who knows? Hey... Is there any other exist?"

"Why not break it, look we have fire extinguisher. Let's smash the door."

"Let's do it."

"What do you think class monitor?"

"Hmm... Let's find something that might open the steel door, if we don't find anything then let's smash it," Yuta thought and said. He smiled.
