INTRODUCTION

Because of a bet, many people suddenly become close to Tobio.
Rules of the bet:
1. Don't let Kageyama Tobio know about the bet.
2. Don't fall in love with Kageyama Tobio.
3. Complete the tasks given by the refeeree (which is Noya and Tanaka)

But, as they said, rules were made to be broken by us.
One by one they fall in love with that blueberry setter.

"What have you done to me?! Kageyama Tobio!!!"
