You and Nagisa were classmates in E class and always got along well, not as friends not as enemies just classmates but Nagisa didn’t like that, he wanted more

Today you was walking home after a party with a few other E class students after finishing a extremely biased exam when you suddenly got knocked out by a bat

A few hours later you woke up tied to a chair when you tried to scream someone put a finger on your lips

“Shh, be a good boy and don’t make a noise” Nagisa said smiling
