After Reaching the Happy Ending, I Was Locked up by the Extremely Possessive Heroines I Had Conquered

Chapter 21: Cohabitation Life

“Good morning.”

“Why are you using polite language?”

The start of cohabitation life began with greetings.

From my experience, when I woke up in the morning and headed to the toilet, a mystery always occurred where I ran into Satori in the hallway. So it was important to greet her without getting flustered.

If I upset Satori’s mood here, I would face serious trouble later.

“Come on, don’t you feel refreshed first thing in the morning?”

“I’m still sleepy at all…”

“You’re the one who wakes up too early, Satori. It’s only five o’clock, after all. That’s way too early, no matter how you look at it.”

“Akira wakes up early too.”

“Well, I… have my reasons for getting up early.”

My reasons involved plotting to escape the island, but I could not tell her that honestly, so I just brushed it off vaguely.

“…”

Satori yawned sleepily, wiped her eyes with the hem of her pajamas, and said,

“I’m going to wash my face.”

“Go ahead.”

“Don’t look.”

“I don’t have a hobby of peeking at someone else washing their face.”

“…I do, though.”

“Hm? Did you say something just now?”

“…Nothing.”

She muttered that and headed briskly to the bathroom.

In that way, my mornings always started with a conversation with Satori. She seemed a bit sleepy, but she gave the same impression as usual.

She did not have high energy to begin with, so there was not much of a gap compared to the daytime.

On the other hand, Toa was like a completely different person.

“…Good morning.”

Three hours later.

I was drawing a picture at the living room table when Toa came in, looking drowsy.

Her voice was faint, and her energy was clearly low. Where had her usual cheerfulness and slyness gone?

She was quiet like a toy with dead batteries only in the morning.

“Want me to make some coffee?”

When I called out to her, she nodded weakly and buried her face in the sofa. She even muttered something like “Senpai, no more than this, okay?” in her sleep-talk.

At that point, I could not tell if she was awake or dozing off again.

It would be easier if she were this quiet all the time.

But that would feel lacking in its own way, so I supposed I had been thoroughly poisoned by Toa too.

For that reason, making coffee for Toa every morning had become my routine lately.

As for Mahiru, she was the type who hardly ever got up, to say the least.

Satori and Toa slept in the same room—the bedroom their parents had used before—but Mahiru had her own room, so she slept and woke up entirely at her own whim.

Her door almost never opened in the morning. It was completely an unopened door.

That was fine in itself. Sleeping soundly without worrying about the time was the true joy of summer vacation, after all. I wanted her to enjoy it to the fullest.

But it seemed the world had its mysteries…

Mahiru, who normally never got up, always appeared when I headed to the ferry terminal. And not just once, but every time.

Each time, she repeated “It’s your fault, big brother” over and over to brainwash me.

No matter how early in the morning it was or whether the sun had risen yet, it did not matter. Even though she was weak in the mornings, she always mustered her strength at the critical moment. As expected of Mahiru.

I could not help but wonder what kind of mechanism made that happen, but I was too scared to ask… and the mystery remained unsolved.

Seven hours after I woke up.

“Good morning, big brother.”

Mahiru finally came down to the living room.

She wore pink pajamas, and her hair bounced in curls. That defenseless appearance was utterly vulnerable, and even being biased, she was adorable.

The way she held her head, worrying about her bedhead, was so age-appropriate that I could watch it forever. If not for the imprisonment aspect, Mahiru was basically a cute little sister.

I wished she would get up in the morning, though.

Mornings aside, we had a rule to eat lunch all together as four.

Mahiru sat next to me, Satori across from me, and Toa next to her. That was how we gathered around the table.

It was basically peaceful, but since we lived together, there were differences in our ways of thinking, and

“Toa, how many times do I have to tell you to stop leaving just the tomatoes from the salad?”

“But tomatoes aren’t tasty unless you cook them.”

“They’re sweet and delicious, aren’t they!”

“Mahiru is too much of a sweets lover. Besides, putting chocolate in omelet rice is weird!”

Today’s menu was omelet rice and salad.

Mahiru was the only one with proper cooking experience, so she was in charge of meals every day, but Toa just could not stand omelet rice with chocolate in it—commonly known as Chocorais.

“…It’s delicious, though.”

“Your taste buds are broken, senpai.”

When I muttered that, she shot me a dissatisfied glare.

“The weird one is you, Toa. This dish is the crystallization of love between me and my brother!”

Mahiru slammed both hands on the table and shouted.

—Chocorais.

It had originated from when I put chocolate in an omelet, and that was how the menu had been devised.

That said, the inside was normal chicken rice, and the egg was normal too.

The only difference was the sauce poured on top.

It was a special sauce made by throwing a bar of chocolate, milk, and soy sauce into ketchup.

It looked completely like demi-glace sauce, but the aroma was overwhelmingly chocolate. The sweet scent was so strong that if you closed your eyes, you would mistake it for a dessert.

For us siblings, who loved sweets, it was the ultimate treat.

“The chocolate adds such depth.”

When I muttered that, Toa pouted and said,

“It’s more sweet than deep.”

“That’s what makes it a secret ingredient and a nice accent.”

“It’s not hidden at all! It’s straight-up chocolate. This is chocolate sauce, not ketchup sauce!”

“…Yeah, it’s definitely chocolate sauce.”

Satori, who had been silent until then, licked some sauce and muttered that.

Toa looked delighted to have an ally, and her expression brightened up as she said,

“As expected of Satori! Tell this taste-impaired sibling pair more!”

“…I like this kind too, though.”

“Satori…”
