3rd Person's POV
(Y/N) (L/N) is a third year English teacher at Karasuno, she studied high school in Karasuno too, seven to eight years ago but she studied college at America for personal reasons. But she was in a relationship with the grandson of the coach in the volleyball club, Keishin Ukai is his name. No students know that she's in a relationship with the current volleyball coach.
"So I was listening to (L/N)-sensei, then Daichi suddenly fell upon entering the class, late. It was so funny"Koushi Sugawara blabbered to Asahi Azumane then Daichi Sawamura gloom over them
"Really? You're never late, Daichi-san"Asahi said as Daichi sighed
"I was just late because of something important"Daichi said as Sugawara laughed
"Important that made you fall upon entering the classroom"Sugawara said as they talked and talked while walking towards the gymnasium, meanwhile, (Y/N) is walking along with Ittetsu Takeda. The advisory teacher of the volleyball team
"I didn't knew that you and Ukai-kun are in a relationship"Takeda said as (Y/N) chuckled lightly
"It doesn't seem like it but we are, he doesn't want any students to know but I guess that changed"(Y/N) said as Takeda looked at her
"He's pretty lucky to have a girl like you, (Y/N)-san. Hope he treats you well"Takeda said as (Y/N) nodded while smiling then looked at the gymnasium. Keishin plan on telling the team his and (Y/N)'s relationship.
"But speaking of which, Sawamura was late in my class earlier......I mean it's the first time he did that. Did something happened?"(Y/N) asked as Takeda looked at her
"Not that I know off, you ask him......I don't really know"Takeda said as (Y/N) nodded
"Okay I'll just ask him later, anyways I think I hear boys from your team already starting practice"(Y/N) said as Takeda nodded while opening the door
"Take-chan!"Ryunosuke Tanaka said as Takeda gestured (Y/N) to come in and so she did then all of them stared at her.
"Eh? (L/N)-sensei? What are you doing here? Sorry for the rude question!"Suga said as (Y/N) chuckled
"It's fine. I came here to observe Takeda-san and you guys"(Y/N) said as all of them tilted their heads
"Where's Ukai-kun? Is he not here?"Takeda asked as they heard a cough behind them.
(Y/N)'s POV
I heard a cough from behind me and Takeda-san, I looked at him and smiled
"Keishin! Your not early as always, what happened?"I asked as he looked at me
"Shut up. Okay guys huddle up!"he said as I chuckled and the guys huddled up, they were curious as to who am I and who am I to Keishin.
"This is (Y/N) (L/N), she's a third year English teacher and advisory teacher of 3-4. Daichi and Sugawara knows her already. She'll be observing us today, she's gonna see how you guys are hard to handle and stuff"Keishin said as I smiled at the guys and two girls. Kiyoko Shimizu is pretty, like gorgeous.
"You forgot something, Keishin"I said as Keishin looked at me
"Huh? Oh yeah, she's also my girlfriend, so she's not available for something"Keishin said as I smiled and all of them looked at me and just stared at me
"EHHHHHHH!?"they shouted as I chuckled at how surprised they were, Keishin was pissed off
"What are you shouting for!? Is it that bad for me to have a girlfriend!?"Keishin asked as I chuckled and smiled
"Well it does says that your a gangster type and I'm the nerdy type, you know same old things. A old looking scary guy like you falls for a nerdy nerd like me"I said as he look down at me
"Huh? What do you mean a nerdy nerd!? More like the nerdy assassin! You move like an assassin, popping up anywhere I go"Keishin said as I smiled remembering the scene where I heard him sing for the first time.
"Hahahah yeah, I like the one that I accidentally heard saw you singing in the rooftop in the second year's building"I said as he looked at me pissed off, he sighed and cooled down for a bit.
Ukai's POV
This girl is the most annoying but a gorgeous girl that I've ever meet, she's probably the demon itself, she always pops up without me knowing, I made the guys train so hard that their bodies gave out, then someone smacked me on the head.
"Keishin! Don't you think you are over doing it a bit too much!? Look at my poor students! They're exhausted!"(Y/N) said as I looked at her
"You made me like this, you know too well when I get pissed off so much, right?"I asked as she chuckled then glared at me
"Then go at me, you idiot! Not on the volleyball players, anyways you all take a rest, I'll just calm Keishin down a bit"(Y/N) said as she dragged me elsewhere, I looked at her
"Where are we going?"I asked as she looks up at me and suddenly kissed my lips!? We were in a classroom.
"(Y/N)? What has gotten into you?"I asked as she look up at me
"I-I just wanted to kiss you........you are precious Keishin......I don't know what I'll do if you are gone"she said as I looked at her
"Baka, don't say something like I'm dying or something, I'll be by your side forever, right?"I asked as she smiled and hugged me, we were pressed against a wall, so I took the chance to flip her and lock both of her sides.
"Keishin?"she asked as I smiled and leaned down.
"I love you, (Y/N). Always and forever"I said as she smiled
"I love you too, Keishin. Always and forever"she said as I kissed her and she kissed back.
~Extra Ending~
All students wondered where Keishin and (Y/N) had gone to until they have to go home, they all saw Keishin's car driving passed them while seeing (Y/N) on the passenger seat.
"I didn't knew Ukai-san has a girlfriend like (L/N)-sensei"Sugawara said as Asahi and Daichi nodded
"What is (L/N)-sensei like?"Shoyou Hinata asked as the third years shivered in fear
"Like Ukai-san said, she's like an assassin who pops out of nowhere........then disappearing like one too........"Daichi said as every first and second years are curious about (Y/N)
"To the fact that she made me stand up for a couple of hours because I was sleeping during her class out of lack of sleep is the most terrifying moment in my life"Asahi said as Yuu Nishinoya looked at him
"More than when Dateko blocked your spikes?"he asked as everyone looked at him
"Yeah more than that!"Asahi said then all of them shivered, meanwhile at the car ride with (Y/N) and Keishin. (Y/N) sneezed.
"I just got chills, maybe someone is talking about me"(Y/N) said as Keishin looked at her in the mirror
"Maybe the students were talking about you"Keishin said as (Y/N) and his hands were intertwined while they laughed.
