Chapter 4: Egg sitting

Tezuka knew something was tugging at the corner of his lips when he heard her say that. But the rules were always meant to be repeated, Sakuno only meekly sat down and listened to Tezuka's very strict rules.

After such a session, Tezuka allowed Sakuno first to use the shower, as he would go back out to do his own laps. This was the true reason as to why Tezuka never runs laps were because he does the laps he gave the rest when he reaches home. But always after he took a break like when he was lecturing Sakuno. Sakuno never complained after the first stay over.

She would always be right at the door with a glass of water before she goes back into cooking. Honestly, Tezuka's mother had taught her everything as if indicating that next time this happens it would only be herself and Tezuka. Sometimes as he talked to Sakuno he would notice his parents and even grandparents trying to get an idea what they were talking about, he suspects that they want Sakuno as a daughter in law.

Tezuka was deep in thought, and at this point no one can see Tezuka because he was running with a hood on. But from underneath his hood, he was smiling a little, how interestingly pleasant the idea was to him. But in his mind it didn't click just yet.

Tezuka walked in through the door and what does he expect? As expected, Sakuno who knows his schedule by now was waiting for him with a glass of water with an apron on. Now he blinked several times. An apron? Wait something doesn't add up with this image. He mentally slapped himself, Sakuno helps out with the cooking but that was only after she had given Tezuka the water. Now she was cooking and doing the same task.

"Tadaima."

"Okaerinasai."

Sakuno smiled at him before allowing him to take the glass of water. Once his hand was firmly around the cup did she walk back into the kitchen and resumed cooking. Now he was getting rather embarrassed. THIS ISN'T CORRECT. His sister is doing every chore like a wife, with this at mind, it reminds him of a saying. Sometimes the mind and the heart work different ways.

These were one of the times where his heart is saying 'I am the happiest man on earth' and the mind is mentally slapping his heart. 'How inappropriate of you to feel such a thing.' Now for a person like Tezuka, which was he most likely going to side? Naturally, with his mind.

He felt ashamed and decided to forget what he had just felt and continue on with his routine. After his shower, he came down and noticed that the food was on the table, but Sakuno was busied in a book. As he dried his hair he casually glanced down at the book she was reading.

He was surprised. "Incubation for the egg." He had almost forgotten about her precious egg that he helped protect. Soon as he thought about it, Sakuno's gentle surprised voice rang out. Clearly she hadn't noticed him reading behind her.

"I have prepared dinner Tezuka sempai."

She leaped out of the armchair and started taking out the dishes as he walked towards the large dining table which was now quite empty after all his family decided on a trip to Paris. They ate in silence and soon together which insisted by Tezuka, they did the dishes together. At this point he had chosen to ask her,

"How is the project?"

Sakuno who turned her head towards Tezuka in response to such a question she blushed a little redder. She was having trouble, she was worrying about where to place the egg and how to keep it well incubated.

She didn't want to ask for help from Ryoma but Tezuka sempai is well read into any form of information right? She believed he would know many things. She always admired Tezuka sempai for his knowledge calm and cool demeanour. It was funny, she was accustomed to be with him from time to time, and she didn't realize that she can read him very well.

When he seems expressionless means the day is going well, when he smiles means the day is going great and when he frowns, well that is when he is worried and if he pinched his nose bridge means he was annoyed and very tense. She knew it all, but it has been so deep that her response was like breathing, a second nature.

"Well, I don't know if I am keeping the egg incubated right."

Tezuka who has read far and wide and had already studied about what she was learning was very reassuring.

"I can help you with your egg."

Sakuno who sometimes doesn't think when it made her happy, her eyes shined brightly as she smiled her best smile.

"Really? So you will help with the egg sitting?"

Tezuka raised his eyebrows in surprise, what? He didn't or technically, he did not say such a thing, but one downfall to Tezuka he couldn't say no to his sweet little sister like girl Sakuno. He swore he was getting weak, but maybe some training might do something about it.

Clearly his heart was muttering darkly. 'There is no cure for love.' Tezuka felt like pulling his heart out and have a small talk with that gloomy thing.

That night Sakuno and Tezuka was busy helping the egg by placing it into the warmest and well protect spot for incubation. Deep inside the egg lay the embryo of the baby, even though it is slowly developing, it knew that outside waiting for it were its parents.

It knew from the voices teaching and looking out for the egg's welfare. It made it in its mind to love them when it sees them.

To be cont...
