(A/N) Okie so before you guys start reading this I just wanted to let y'all know (if you didn't see my announcement) that this will be the last part of the flashback in which they are in middle school 3rd year, basically the present will be 1 month before the exams. Okay? Oh! I almost forgot- after this chapter I will then put all the information regarding the characters like about (your/name) or Rinkashifu.

Thank you for listening and now onto the chapter!

Recap

~~~~~~~~~~~~~~~~

'When will you finally be at your limit Deku!?' You thought 'When will you give up and move on so we won't bother you?! You are so determined! It's so annoying!! Just give up already!' You looked away seeing your brother still shouting at the green haired boy but Izuku still had his eyes locked on you. 'Why!?'

Izuku just stared lost in thought forgetting that Kacchan had been yelling at him. 'Why did you have to change Rinki? When will you come back? Where's the innocent girl I had a crush on back in preschool? Where did you go..?'

After class had finished-

~~~~~~~~~~~~~

It was 3:32pm most of your classmates had already left the school to return to their homes. Now the only people left in the classroom was you, Katsuki, 2 of his friends, and Izuku. You and Katsuki had been talking when you spotted Deku on his phone, Katsuki turned to see what you where looking at as you sighed,

"What's the nerd up to now I wonder.. wanna go see?" You said with a small smirk. Katsuki immediately knew what you meant as you both walked over to the green haired boy.

"...some notes down before I forget anything, hm." is all you managed to hear as he put his phone back in his pocket and lifted up a notebook. "Uh!" He made a sound surprised that his notebook had been snatched from his reach. He looked up only to see that you had been the one to take it from his grasp. You looked down at him with an annoyed look on your face. He just stared at you dumbfounded. Until Katsuki took the book from your hand and said,

"I don't know what you think you're doing Deku, but we're not done." He spoke with a deep voice that honestly surprised you as it almost seemed calm in your eyes.

"Whatcha got? His diary?" One of your brother's 'friends' asked as he walked up with the other guy who had been listening to you and your brother talk after class.

"Uhuh.." Deku made a small noise as he tried to reach for the notebook in Katsuki's hands but Katsuki just pulled it farther away from the green haired boy. 

"Huh? Don't tell me you're taking notes on how to be a hero?!" The same guy spoke up again. "That's so pathetic! Haha!" The other guy started laughing too but you and Katsuki just continued to glare at Deku.

"He's delusional!" The other one finally spoke up. Izuku stood from his desk.

"Yeah, real funny guys! Just give it back-" Deku tried once more to try and grab it but before he could Katsuki made a small explosion which seemed to have turned the book to ashes but he just burned it a little. "AHHH!!" Deku screamed. This annoyed me even more.

"Jeez why do you even need that notebook anyways? You stupid not to remember it so you write it all down instead?" You spoke up with a growl at the end.
