When Korosensei heard that Nagisa's mother wanted to talk to him, Korosensei had a flashback the day he met Hiromi.

He was on an assassination mission to kill a mob boss. While he was scouting him at a restaurant, a nice, young, and beautiful woman sat next to him and introduced herself, "Um hello. My name is Hiromi, I hope you don't mind me sitting here it was the only seat available" she said while looking down and trying not to make things awkward.

Korosensei replies with a smile, "I don't mind and nice to meet you Hiromi-san, my name is Yusuke."

While Hiromi was talking to the assassin in disguise, "Yusuke" never took his eyes off the mob boss but also he couldn't take his eyes off of Hiromi yet he didn't know why...

He began questioning himself, "Wh..what's going on with me, why can't I take my eyes off her. No! I need to focus on the mission but still what's going on with me?!"

As "Yusuke" was trying to figure out what was wrong with him the mob boss had left and "Yusuke" began to panic until he felt a gentle touch on his shoulder. He didn't know who it was or if he was in danger. He asked himself " Could it be the mob boss found out that he was here to assassinate him and that he was only seconds away of dying!"

"Yusuke" was ready to face the truth as he got his blade ready to strike as fast as he can but when he turned around he realized that gentle touch was from Hiromi. "Yusuke" forgot that she was still next to him.

Hiromi asked " Are you okay Yusuke-san, you seemed worried? Is this your first time sitting next to woman" she said with a smirk on her face.

"Yusuke" hastily says "No it's not and I just lost something and I need to quickly find it before it's too late."

Hiromi smiles, "Then why did you turn all red when I touched your shoulder?" she asked

"Yusuke" said, " I..I don't know what you are talking about anyways" he stands up. "I need to go now. I really need to keep searching."

Hiromi grins "If it's that guy you've been staring at for the past hour, he went through the back while you were spacing out."

"Yusuke" was shocked, "I was not spacing out and thank you for your time." "Yusuke" leaves the table fast and runs through to the back exit. While he is running, he could hear a faint voice, "We should meet again, I live around here have a great night Yusuke-san"

Hiromi smiles and leaves the restaurant through the front door.

"Yusuke" looks at her while he opens the back door. As "Yusuke" makes his way to the ally behind the restaurant, he could see the backlights of the mob boss's car turn the corner and he chases after it.

Hiromi is leaving the restaurant and as she is going to her car she sees "Yusuke" chasing the car and she yells "Yusuke-san I can give you a ride!". But "Yusuke" ignores her and he continues chasing the car. He writes down the license plate down as he gets exhausted.

As he slows down he hears that voice again, "Hop in and we can catch that car!"

"Yusuke" is shocked and he slowly goes in the car and as he closes the door. The car speeds up. "You're a crazy driver" he yells but she is too busy and yelling at people to get out the way (like a boss).

"Yusuke" is stunned but he smiles a little bit until he sees the car.

"Slow down!" he yells at her but she was going super fast when she stopped the car began to spin around and...

"Korosensei everyone is waiting for class to start!"

''Ahh yes thank you Nagisa-kun" he politely replies as he dodges the bullet Nagisa fired at him. He needs to teach and avoid getting assassinated by the students of Class 3-E. Just a normal day here at Kunugigaoka Junior High School.
