A/N: I never thought I would write nostalgia but I remembered this AU where Onodera and Takano sort of adopt Onodera's cousin's baby. I found the archive on the ask blog I sent these headcanons too. Those who frequent the sih and jr blogs on tumblr know which dirty confessions blog I'm talking about. Oh man this was around last year when this came to mind but I want to write fluff. Either way, this is more of a drabble series.


1. Start

Hanako Amaya née Onodera, handed her diaper bag into Onodera's awaiting arms. Her arms felt lighter without the over packed bag but preparation was key. She heard him grunt about the weight, she gave him a sheepish smile. Her comment on his weak muscles went unsaid but the implication remained. Onodera shrugged his shoulders and placed it on the shoe rack. Playing off the strain it gave his arms when he held it, he laughed, joking about the contents of the bag.

She maneuvered the stroller inside of the the apartment, careful in keeping the jostling down to a minimum. Onodera helped her move it up into the wooden flooring and set it aside. The baby giggled from behind the plastic covering over the front of the stroller. This prompted Hanako to remove the covering, giving Onodera a view of the smiling little boy.

Onodera awed, he reached out his hand and caressed those chubby cheeks. "Oh wow, you're way bigger now than the last time I saw you. You even have a full head of hair now. I know your mother hid your baldness with beanies and hats." Hanako nudged Onodera but didn't hide her amused smile. "How old is he again? Seven months?"

Hanako checked the undercarriage of the stroller for any misplaced items. "Nine months old." She straightened herself up and smoothed down her slacks.

"So...can he sit up now?"

"Oh yeah. He can sit up, babble vowels, and hold his head upright. He can crawl around now so I suggest keeping an extra eye on him."

"Will do." Onodera stuck his tongue out at Ryota and did some funny faces. "Oh! So he might walk?"

"Don't hold any hopes on that happening." Hanako checked her phone for the time. "Thank you so much for doing this for me." Hanako fought the urge to rub her hands on her face. She caught her appearance in the hallway mirror and noticed strands of hair peeking from her bun. She scrambled in fixing it up. "I called multiple people and everyone is busy. I wouldn't have sprung Ryota on you if I didn't have someone to watch him. My husband got called into work as well."

Onodera smiled as he unbuckled Ryota and scooped him out. Ryota's little hands tapped his cheeks and wiggled in his arms. "It's no problem. I don't mind looking after the little guy. He's so calm and happy. He makes my job a lot easier. We'll even take a long nap after lunch is over."

"Remember, Ryota loves his little stuffed kitty. Never forget to have it on you at all times." Hanako advised Onodera as she brushed Ryota's black wisps of hair to the side. "His feeding and sleep schedule is in the diaper bag. I put in jars of his usual baby food and formula. There's some new outfits in case he spits back up his food or poops through his diaper. Um...what else am I forgetting?"

Onodera assured his frazzled cousin before she rambled on. "Hanako, it's okay. I'm sure Ryota and I will be alright for today. It's not like I'm going anywhere." He nuzzled his nose against Ryota's cheek, causing the baby to giggle. "Don't worry so much. I'm sure you didn't forget anything. Besides, there's a convenience store in the corner to buy anything that's missing."

Hanako kissed Ryota's forehead and held Onodera in a light embrace. Her relief showed through every inch of her form. "Thank you again, I owe you big time for this favor. I'll give you a call if I have to stay in longer at my job. I told Ryuusuke that you have Ryota for the day."

"Is he going to pick him up?"

"I'm not sure, it depends on who finishes their work first." Hanako fiddled with her blazer and inspected her bag. "Don't be surprised when he rings your doorbell."

Onodera held onto Ryota's hand and used it to wave at her. "Okay. I'll give you updates if anything happens. Probably every few hours so I don't disturb you. I'll see you later, Hanako-chan."

"Bye, Ritsu! Bye, Ryo-chan!" She shut the door and her footsteps disappeared the more she ran down the hallway.

Onodera smiled as he poked Ryota's nose. "How about a small lunch?" Ryota gurgled in response. "Alright! Do you like noodles? What am I saying? I'm sure you're used to mashed veggies. Here's hoping your mom made them taste good. Unseasoned vegetables is just not done."
