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

Chapter 40.2: When I Proposed Leaving the Island to My Stepsister

If she had prepared the environment, that probably meant our house could now connect to a signal.

Or perhaps it was a pocket Wi-Fi or something?

Either way, with me not possessing any communication devices, I had no means to verify it.

“When exactly was that?”

“Quite a while ago.”

The way she avoided giving a specific date made it seem utterly suspicious, but in the end, it all came down to the three great families being at fault, so the essence had not changed from before.

“By the way, do you know why Satori is so knowledgeable about surveillance cameras?”

“Yes. I heard Satori’s aunt started a company outside the island.”

“A company?”

“They make cameras there, and she’s installed them all over the island. So I think that’s why the Jindaiji family has extensive knowledge of surveillance cameras.”

“………………………………..”

Was there such a setting in the original work?

At the very least, I had no memory of it.

Well, it was true that the three great families, including the Jindaiji, conducted business outside the island, which was precisely why their influence was so strong, but I never imagined that influence would be of the type that manufactured surveillance cameras. Nor could I have.

But if that was the case, it made sense of the abnormal number of surveillance cameras.

And it also explained why Mahiru was so unusually well-informed about my actions.

“Hey, Mahiru.”

I slowly placed my hand on her shoulder and made my proposal to my wide-eyed, head-tilted little sister.

“Shall we study portrait rights?”

The conversation had veered off track, but my true purpose was not studying portrait rights; it was persuading Mahiru.

“What do you mean, you want to talk alone?”

“Now, now, just sit down for a bit.”

To be safe, I revisited the top of the cliff, outside the surveillance cameras’ range, and sat side by side with Mahiru on the rocky outcrop, turning my gaze to the vast ocean stretching before us.

Each time the waves crashed against the rocks, white spray rose, and the wind carried the scent of the tide.

This smell, this scenery—all of it was memories with Mahiru.

“It’s nostalgic, isn’t it?”

I said while gazing at the distant horizon.

“Yes. It really is nostalgic. After all, this is the place where you became my brother. It’s a view I’ll never forget for the rest of my life.”

There was an intensity in Mahiru’s voice as she murmured “for the rest of my life.”

A faint light dwelled in the depths of her eyes, with a seriousness as if she were reaffirming an old vow.

“—For the rest of my life.”

It did not seem like a wise strategy to keep filling her possessive gauge like this, so I hastily changed the subject.

“You know, Mahiru, I want to gaze at so many more sights with you. The sea is great, but for example, Tokyo Tower, or Tokyo Skytree, or the Kaminarimon Gate in Asakusa.”

“That’s all in Tokyo, you know?”

Faced with her sharp gaze, I involuntarily averted my eyes.

“…………Well, besides that, I want to eat delicious things together. Like Edomae sushi, or monjayaki, or Tokyo Banana.”

“Those are all Tokyo foods too, you know?”

“I’m a total Tokyo enthusiast.”

“……………………………………………………….”

When I cracked a light joke, Mahiru suddenly fell silent and looked down.

Her expression and gesture were so terribly frightening that I raised my voice dramatically to dispel the silence.

“Anyway!”

“………………………….”

“I want to have so many more experiences with you, Mahiru. So here’s my proposal…”

I swallowed hard and turned my entire body to face Mahiru.

Then, extending my trembling hand, I offered it toward her.

“With me—”

I slowly regulated my breathing,

—won’t you leave this island? And live together forever?

The instant I expelled those words, a torrent of emotions assailed me, and I could not breathe properly.

Feelings indistinguishable as fear or anticipation churned together, making my breaths shallow.

“…………………………………………..”

She looked down at my hand and slowly blinked.

Then, after a while—,

When she raised her face, a smile graced her eyes.

However, it was not one of relief or joy. It resembled anger in some way, yet it was not furious; it was a calm, quiet emotion.

“What are you saying?”

After a stretch of silence, Mahiru murmured softly.

“Brother, you’re saying something strange.”

Her voice was gentle, yet chillingly cold,

“Because we are siblings. From birth until death, we are always together. That’s what siblings are, right?”

Mahiru took a step forward.

Then, seizing my hand forcefully with both of hers, she gripped it with such strength that her fingertips dug in, as if declaring she would never let go.

“So of course I’ll go with you even without you telling me. Of course we’ll live together forever!”

With that, Mahiru smiled brightly.

That smile was so utterly natural, so fervently warm.

“Brother”

“—I’ll be by your side forever and ever!”

And so I succeeded in persuading Mahiru.

Whether this could truly be called persuasion remained questionable, but in the end, all was well that ended well.

By the way.

“Brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother brother…”

Could you let go of my hand soon?

We’ve already made it back home, you know?

We’ve arrived at my room, you know?

I need to use the bathroom, but you won’t let go, you know?

It seemed Mahiru’s sibling love was just a little too strong.
