Interlude 1: Lets Make Sure Hes Ours And Ours Alone

It had been several days since my sister and I had gotten caught up in that random street attack. We’d found ourselves in a situation where it wouldn’t have been surprising at all if we’d been killed.

When our lives had been in danger, and our memories had begun flashing before our eyes, like a montage of our entire lives, we’d genuinely believed that this would be our last day.

But we’d been saved.

By an ordinary boy who was both our classmate and someone in the same grade: Yagami Ryoya.

There had been plenty of people around at the time, but Yagami-kun had been the only one who tried to save Riona and me.

And he’d protected us even at the cost of his own life.

After seeing him like that, how could anyone possibly expect me not to fall in love with him?

Throughout my life, there had been plenty of people who liked me, but I’d never once experienced the feeling of falling in love with someone myself. As a result, I’d never had a boyfriend, and honestly, I’d never particularly wanted one either.

But now, I wanted Yagami-kun more than anything in the world, with every fibre of my being.

I’d always been more possessive than most people, so I wanted to make him mine and mine alone. I didn’t want anyone else laying even a finger on him.

There was, however, exactly one exception in this world: my younger twin sister, Riona.

Riona and I had come into this world when a single fertilized egg split into two.

In other words, we had originally been one and the same. You could say we were two halves of a whole.

That’s why what belonged to Riona also belonged to me, and what belonged to me also belonged to Riona.

As identical twins, our tastes and preferences were naturally quite similar. And just like me, Riona had fallen hopelessly in love with Yagami-kun.

“Is the remote monitoring app working properly?”

“No problems so far.”

“That’s great! Now, even if some nasty little bug tries to get close to him, we can get ahead of them!”

After leaving Yagami-kun’s hospital room and returning home, Riona and I had been having that very conversation.

When we’d registered our contact information earlier, Riona had secretly installed the app on Yagami-kun’s phone.

The remote monitoring app was originally developed for things like parental supervision and theft prevention. It allowed someone to secretly view emails, SMS messages, LINE conversations, browsing history, and other activity on a smartphone.

We were planning to misuse it to keep an eye on Yagami-kun’s activities.

It even had a function that allowed the app itself to be hidden, so we could cover our tracks. However, there was one problem.

The app was constantly running in the background. Because of that, it might have been causing problems such as slowing down his phone or draining its battery unusually quickly.

Still, since his phone was fairly old, he might have just assumed the battery was wearing out.

“By the way, he’s currently searching the internet for ‘Exchanging Contact Information with a Girl: Chances of Getting a Girlfriend.’ It looks like he wants to date us.”

“So he really is a normal boy, after all.”

Needless to say, both Riona and I intended to date Yagami-kun.

In fact, we wouldn’t allow him to date any girl other than the two of us.

“Let’s make sure he’s ours and ours alone.”

“Yeah. We’re not giving him to anyone else.”

For now, we’d continue visiting him every day after school, starting by getting to know him better.

Yagami-kun hadn’t seemed particularly opposed to spending time with us, either. If we kept seeing him under the pretext of visiting him in the hospital, we should be able to grow even closer.
