My Hero Academia: Mizumi's Story

ShiZuNari

3rd Person
After a wild night in the bedroom with his girlfriend and new boyfriend, Shinso realizes he has some thinking to do. He's never had feelings for another guy before, but Kaminari makes him feel something. He's finally starting to understand why his girlfriend is in love with the boy. After Kaminari had confessed his feelings for Shinso the day before, Shinso decides to take some time to think about the future, so he leaves Mizumi and Kaminari alone for a few days. Since they go to the same school and their dorm buildings are right next to each other, it's a little hard to avoid them. But he needs time to think about some things, and communicates that he needs to be left alone without explaining why.
Mizumi and Kaminari worry about Shinso and cling to each other for emotional support. They become more inseparable than ever, refusing to leave each other's side.

"So, are you guys planning on adding another girl to the relationship to even things out?" Mineta asks one evening while Mizumi and Kaminari are relaxing on the couch after dinner.
"Nah, I'm good with the way things are right now," Kaminari says. "My little spark is the only girl for me~"
"Awww~" Mizumi wraps her arms around her boyfriend and kisses his cheek.
"Well if you ever change your minds, I'm sure Jiro would fit right in~" Mineta smirks at the perverted thoughts of Mizumi and Jiro being girlfriends.
Kaminari blushes at the mention of having Jiro as his girlfriend. Mizumi is aware of her boyfriend's past feelings for the other girl and can't help feeling jealous. She has a lot of respect for Jiro as a friend, but there are no romantic feelings.
"Yeah, that's not happening," she says. "Kyoka and I are just friends and I'm not going to try to force myself to develop feelings for her."
Kaminari laughs to himself, causing Mizumi to let go of him. She gives him a warning look, trying not to show her jealousy. Mineta runs out of the room when he realizes he might have accidentally started a fight.
"I don't know how Toshi can do it, watching his girl fall in love with another guy. How does that not drive him crazy?" Mizumi says, getting up from the couch.
Kaminari follows her, trying to calm her down. "You know why. We both want to make sure everything is gonna be okay in case something happens. We've had this conversation before."
"Well, I'm not like that. I can't stand the thought of another girl touching either one of you. I don't care if it sounds selfish and possessive, but you're mine. You both are, and I can't risk losing either one of you to another girl if you decide you like her more."
"Baby, you know that's not gonna happen. You're our girl, and you know that. We both love you so much and neither of us are going to leave you for any reason."
"If that were true, then why did Toshi abandon us?" Mizumi breaks down in tears, wondering why the love of her life would leave her. As happy as she is with her second boyfriend, it's not the same without both of them.
Kaminari hugs Mizumi tightly, rubbing her back while she cries. "I don't know what happened, but I'm sure he'll come back to us."
"Was it something you said to him? He was fine until that date with you." Mizumi looks up at Kaminari with her accusation. She knows it's nothing she did wrong, so it must be his fault. "What did you do?"
"Nothing, I swear! And anyway, how was it my fault? You're the one that tricked us into going out without you. Maybe he's still mad at you for that. Are you really sure it's not your fault?"
Mizumi pulls away from his embrace, looking up at him with a shocked expression. "Excuse me?"
Kaminari immediately realizes his mistake. "No, I'm sorry. I didn't mean that." But it's too late. He watches helplessly as his girlfriend storms off.
"Goodnight, Kaminari." Mizumi disappears into the elevator and hides in her room while she cools herself down from the argument. She hasn't called her boyfriend by his last name in awhile, and she knows she's being too harsh. 

She takes some time to calm down before she knocks on her boyfriend's door.
"I'm sorry..." Mizumi's voice is shaky and she looks ready to cry again. She keeps her head down as Kaminari lets her into his room. He leads her to the bed and sits next to her.
"It's okay. I'm sorry too." Kaminari keeps calm, despite being a little upset. He appreciates the apology, but doesn't blame her for the way she acted. She was already upset, and he knew he made it worse.
"No, it's really not...you didn't deseve that..." Mizumi positions herself on her knees, kneeling in front of him. She gently rests her head on his knees, looking up at him with teary puppy-dog eyes.
Kaminari's eyes widen at her submissive display. He gently pets her head, reassuring her that he is not mad at her.
She smiles a little and leans into his touch. "Can you do me a favor? Don't let me talk to you like that ever again. If I get an attitude with you, please put me in my place."
"Of course. You know I will."

When Shinso comes back, Kaminari and Mizumi pounce on him, causing him to fall onto his back with them both on top of him. Kaminari is happy to see Shinso, but Mizumi is still upset. The tension between Mizumi and Kaminari was high while Shinso was gone, and he's about to hear all about it.
"Stupid jerk...do you have any idea how worried we were? We were so afraid we were never gonna see you again and we didn't know what to do without you." Mizumi scolds.
"I know, I'm sorry. I just needed some time to think about things and figure myself out. I promise I'm here now." Shinso gently grabs Mizumi by the chin and pulls her into him, kissing her passionately. She melts into the kiss, running her hands through his hair.
"Don't scare us like that. We can't lose you..." Kaminari adds Shinso pulls away from Mizumi. His golden eyes widen as Shinso pulls his face closer and kisses him too, but with a little more dominance. Mizumi watches happily as her boys share their first public kiss.
Shinso chuckles as his girlfriend and boyfriend kiss his cheeks at the same time after the passionate kisses. "You two are gonna be a handful, you know that?"
"Then it's a good thing you have two hands~" Mizumi giggles.
