It was a rainy day. You were in class paying attention to the teacher's explanation. Until you feel a paper ball hit your head and fall to the floor.

You look in the direction the paper ball came from and notice Ryusei smiling at you in an amused way.

You took the ball and were going to open it, but The teacher saw it and called both of your attention.

"You two, to the principal's office now!" The teacher said in a serious tone. Ryusei sighed.
