Sooo, I absolutely love OtoyaxHaruka and the idea of them having a family. It's very much inspired by the cover photo which by the way doesn't belong to me. To start off here are the Ittoki children's names and ages:

Otoya and Haruka: roughly 40 years old

Takuma: 17 years old (7 minutes older than his twin, Takeshi)

Takeshi: 17 years old

Akemi: 13 years old

Yuriko: 12 years old

Junpei: 7 years old

Prompt: Ittoki Takuma asks his mother, Haruka if she's pregnant again...

Takuma stared intensely at his mother who stood by the sofa as she changed the channels. He laid on the couch with his favourite manga after a long day of school. Noticing his gaze, Haruka turned to him and tilted her head in confusion.

"Takuma? What's wrong?"

Without hesitation, he deadpanned and asked, "You're not pregnant again, are you?"

"Takuma, t-that's rude! I'm not!" Haruka exclaimed while her face turned as pink as her hair. Takuma was not satisfied with her answer but before he could open his mouth, Haruka interrupted him.

"Ah! I think I missed your dad's replay of yesterday's show. I guess I'll just relax in my office for now!"

She quickly put away the remote and ran upstairs. A loud door slam echoed in the entire house that caught Takuma's other siblings' attention.

"What was that?" Asked Junpei from the dining room. In his hands was a new book he was reading as per Uncle Tokiya's suggestion. Takuma groaned as he sat back up on the couch.

"Uhh… I think we might be getting a new sibling." Just as he said that, Takeshi, Akemi, and Yuriko holding a soccer ball came in from the front yard. They had various reactions.

"Honestly, I'm not even surprised at this point." commented his twin with a lighthearted laugh.

"W-What?! A-another one?!" Akemi's eyes widened and she looked away to hide the embarrassment on her face.

"A new little sister…? T-that's good." Yuriko lit up and smiled shyly.

"Yuriko-nee! We're not getting a little sister. It's going to be a little brother!" Junpei retorted. His older sister frowned at him.

"... No. I want a little sister."

While the two youngest Ittoki siblings bickered, Akemi crouched in the corner holding her very heated face. If one closely listened to her, they would hear her whisper to herself "H-how m-much d-do they love each other… Six k-kids w-worth? Isn't that too much?!"

Takeshi approached Takuma and sat beside him with a smile.

"You always complain about getting more siblings but you're the one who spends time with them the most, especially when they were infants." Takeshi said.

"S-Shut up…"

Takeshi only laughed.

Later that night…

Otoya arrived home late after his latest job. When he entered the master bedroom, he was surprised to not see Haruka in bed. He saw the bathroom light turned on with the door slightly ajar. He walked into the bathroom.

"Haruka?"

"Thank goodness…" He heard her say before she noticed him through the mirror. She turned around.

"Otoya-kun! Welcome home." She whispered happily. They shared a hug before she pulled slightly back while still in his arms.

"I'm home. What's wrong?"

Haruka laughed nervously while looking to the side. She answered shyly, "T-Takuma a-asked if I was pregnant again. S-So I had to check."

Otoya's eyes blinked and he could feel his heart beat faster.

"...S-So?"

"I'm not pregnant." She showed her pregnancy test that was negative. They both sighed in relief before laughing quietly to themselves. After a minute, Otoya smiled at Haruka and rubbed his nose against hers.

"Did you want another one? Maybe two?" He asked playfully. Haruka lightly smacked his shoulder as she pouted.

"Mou, at this point our kids might as well become Starish 2.0."

Otoya grinned, "So… You're not saying 'no.'"

Otoya would have laughed louder upon seeing her red face but it was late at night and the kids were all asleep. He patted her head.

"I'm just kidding. Come on, let's go to sleep." Haruka nodded as she let him lead them back into their bedroom.

Soon after they got themselves settled in, Haruka was ready to fall asleep when Otoya turned around to face her with an excited smile.

"... What about adoption?"

Haruka giggled and snuggled in closer to Otoya. Almost out of habit, Otoya immediately put his arm over her.

"I'm not opposed to either really…" She whispered before she fell asleep.

Otoya smiled gently and followed shortly after her.
