[1 year Later]
"Sora-chan, one more bite!" You gave the spoon full of baby food to your 1 year old daughter as she tries to take a bite.
"She's so cute." You smiled as you continue to feed your daughter, suppressing the urge to pinch her cheeks.
"Just like you." Haruka said as he fixed the table preparing breakfast for you.
"Wh-What?" You looked at him in surprise.
"She looks just like you." Haruka smiled causing you to blush.
"Y-You are just teasing me!" You looked away trying to ignore your husband.
"Hmph." Haruka sighed in content, it was just an ordinary day with the family again, and it was nice.

"Makoto's mother used to tell me that if the child looks more like the mother, that means the father really loves the mother." He said softly while watching you and Sora-chan then glancing at a wedding picture showing you in a simple wedding dress and him, in formal clothes while carrying the 6 month old, Sora .
Haruka started to remember the past events, the sudden pregnancy news, the crazy adventures of you and him, and when he proposed to you after graduating.
The small apartment at Tokyo feels much better with you and Sora-chan living with him. Makoto also lives next door, Gou, Rei and Nagisa, continued the swim club back at Iwatobi, Rin continued to study in Australia and Haruka continued his dream to be a professional swimmer.
"Look at the time!" you glanced at the mackerel design clock in the wall.
"You're leaving already? Then just let me wrap your breakfast…" Haruka quickly wrapped your breakfast and kept it in a paper bag.
"Here you go." He handed the paper bag to you as you took your bag full of papers.
"Thank you! I'm going now! Take care of Sora-chan!" You smiled and gave your husband a kiss causing him to blush.
"Still blushing? It's already been a year!" You giggled as you kissed Sora-chan on the cheek.
"Bye!" You said while you closed the door. You were excited to go to class today because you wanted to be a [INSERT DREAM PROFESSION HERE]. Studies maybe hard but the more it gave you the inspiration to become a [insert dream profession here] and for you to take care of your family in the future.

…

[Meanwhile]

Haruka sighed; he still was not used to this gesture every day.
He sat down and gently wiped Sora's mouth. He was glad to spend time with his daughter since he had no class today.
"Sora, look… It's water." He said while showing her a glass full of water. This only caused Sora to blink at him in confusion.
"When you look at it, you feel so free (na splash kasaneta)." Haru continued, and when hearing the 'free' word, Sora giggled.
"One year and still has not said a word…" Haru sighed a bit then he gently stroked Sora's hair.
Sora smiled back at her father and he smiled in return but then Sora started to look away.

"Ah!" Sora shouted while trying point at the wedding picture.
"The wedding picture?" Haru stood up and took the picture behind.
"Ah! Ah!" Sora said, as Haru showed it to her.
"Ohhh…" Sora looked curiously. "Mmph!" She pointed at [Name].
"That's Mama." Haru watched his daughter in admiration.
"Ah! Ah! Ah!" She tapped the picture while looking at him.
"That's Papa, while he is carrying Sora-chan." Haru smiled as he patted her head.

"Ohh… Pa…Pa…" Sora mumbled and Haru's eyes widened.

"A-Ah, You talked! Sora-s first word!" Haruka gasped as Sora continued to look at the wedding picture.

"Pa…Pa!" She smiled while looking at her father.

"Y-Yes, I'm your papa." Haru blushed as Sora's hand held him.

"Papa!" She smiled and it was one of Haruka's greatest days.

…

[LATER]
"WHAAAAT?! YOU DIDN'T RECORD A VIDEO OF SORA-CHAN'S FIRST WORDS?!" You huffed as Haruka held a sleeping Sora in his arms.
"I recorded her fifth word in saying 'papa' though." He said tossing you his phone as you watched a video of Sora saying 'papa' when she looks at her father smiling.

"Oh my gosh, this is so beautiful!" You blushed as you replayed the video again.
"She really is a daddy's girl." You sighed while you looked back at Haruka.
"I told you that I wanted a daughter because... She would look as… b-beautiful as y-you." Haruka looked away blushing.
"Hmmm… Maybe I also wanted a son." You interrupted. "I want him to look like you. A little Haruka! so cute!"
"Then we can make another one." Haruka said.
"I'm always ready to have se-" You suddenly covered his mouth.
"S-Sora's here!" You gasped as Haruka looked at Sora sleeping in his arms.
"Sorry." Haruka blushed.
"B-Be careful…" You said softly.
"Y-Yeah…" He replied.
[What he actually means is... "I'm always ready to have several children".]

"B-But…" He continued.
"I-I'll work hard… so that we can have a big family." Haru said with determination.

…
[SEVERAL YEARS LATER]

True to his word, several years later, you checked with the doctor on your fourth pregnancy, to find out that it was a boy.

"Maybe we can name him, 'Pool-kun'." Haruka mumbled as you watched him swim around the pool with your three children.
"When, I was pregnant with Sora-chan, you wanted to name her 'Saba'! When I was pregnant with Ren-chan, you wanted to name her 'Water-chan'! AND then when I was pregnant with Mizui-chan, you wanted to name him 'Ocean-kun!' Now this?!"
"Don't worry, I'll protect 'You, Sora, Ren, Mizui and Pool-kun!" Haruka's eyes sparkled as you looked at him furiously.
"A-Alright… It's Pool-kun." You rubbed the growing lump on your stomach as Haruka looked at you giving a smile.
"Yay! A new brother! Pool-kun! Pool-kun Pool-kun!" Sora laughed as she was in swimming pool looking at you.
"Yay! Pool-kun!" Ren laughed as Haruka embraced her along with Mizui on the opposite side.

…

[TIME SKIP]
You smiled as he held his fourth child in the hospital, the room was occupied with your three children with Gou and Makoto.
"You just look like me." Haruka smiled as his eyes sparkled again. You knew that the old quiet house at Iwatobi is going to be much different from now on.

The hilarious part at the end was when Haruka named your fourth child 'Shiro' instead.

"I guess this time... The child looks like the father because the mother loves the father so much." Makoto whispered to Haru's ears causing him to blush.

FOR THE FUTURE THE END

A/N: This is the end of my crack multi-chapter story, thank you for commenting/liking this.
I really had a headcanon that if Haruka would be a father, he would be a father of 5 children (but I made the story 4 children instead). The names are random again but I researched the meaning of the names in kanji:

蓮 (Ren) "Water lily" (second child, daughter)

水居 (Mizui)"place where the water is" (third child, son)

四郎 (Shiro) "fourth son" (fourth child, son) but technically, he is not the fourth son, but the fourth child.

After finishing her degree, Reader-chan works part-time with her [Dream Job] and Haruka continues to be a professional swimmer, they both move back to Iwatobi but since Haruka did not want to leave his children behind (unlike his parents) he brings them (as much as possible) to all his competitions around the country and abroad.
