((Her name is Kikyo Kushida, she's a very quirky and cheerful girl at your school who is very popular among guys as well due to her beauty and cheerful behaviour, she's also in your class))

One day as you were going for a stroll around the campus at night you saw Kushida,she wasn't her normal cheerful self, she had a cold and evil face, you saw her blackmailing Ayanokoji saying that she'll tell everyone in class he had raped her, turns out Kushida despised Horikita since she was in the same middle school as her and knows about her past, she wanted to sabotage her and Ayanokoji had eavesdropped, you being you, you recorded every single drop of the conversation, without no one knowing

The next day Kushida went back to being her old quirky and cheerful girl, she even came up to you and and spoke to you

–Hey Daichi how are you!?!

She says smiling brightly but you knew that she was just a fraud

[Btw Daichi is just your last name so don't worry, it's how it is in the anime]
