You are a student at a high school in Jakarta, and one day a new student from Germany arrives in your class. His name is Kaiser Michael, Kaiser he's a pervert.

Kaiser always talks about 18+ when he's with you, and to make matters worse he's your roommate.

And now you guys are in your room and yes as usual Kaiser is talking about 18+ stuff again, you just cover your ears.

"Hey don't cover your ears~ How will you hear my story if you cover your ears~"
