v3 Chapter 10: A warning from my younger sister ②

“Ah, this brings back memories,” Risako murmured as she looked around the park.

“Yeah, we used to play here when we were little… So, what’s up?”

“…”

Risako took a seat on the swing.

“Say, what’s the relationship between you and Nishimiya-senpai… like, are you like, siblings separated because of an incident?”

“!!… How did you?”

(As far as I know, only Hina-ane or I should know about this. Did Hina-ane spill the beans?)

Seeing Kousuke’s confusion, Risako laughed.

“Haha, did you think it was Oneechan who spilled the beans?”

Caught off guard, he stammered.

Risako laughed and continued, “She will never, you know it too, right? Oneechan’s attitude had become just too different, and same goes for you, the way how you are always sticking to Nishimiya-senpai. So, I did some digging, and as expected…”

She casually pulled out a photo showing Kousuke and Ren holding hands.

“Is this Ren-nee? Aren’t you guys pretty close!”

Risako jumped off the swing with excitement and approached.

“It’s really great, isn’t it? To finally reunite with your real sister!”

“Guh… Gaah!”

As Risako approached, she grabbed Kousuke by the neck, squeezing and slamming him against the fence with force.

“…Do you remember what you said, how you wouldn’t forgive anyone who hurts oneechan?”

Risako tightened her grip, and though Kousuke tried to escape, her hold was so strong that it wouldn’t even budge.

“Say, Kousuke, now that your real elder sister’s back, is my oneechan no longer useful to you? What is it… say, cmon say~, say~, SAY~?”

“Guh… That’s ..not… true!!”

Kousuke desperately stared at Risako.

“…Fuu, it seems like you’re not lying.”

Risako released her grip and stepped back.

“Guha… ha—ha…”

“Well, consider this a warning from Hinako Toujou’s little sister. Of course, from now on, the relationship between oneechan and Kousuke will inevitably change to being made for each other.”

“That’s not possible…”

“That’s possible, so Kousuke, when that happens… please, be as kind as possible to oneechan, okay.”

“Risako… I understand, but my relationship with Hina-ane won’t change. After all, I was able to recover only because of her.”

“…I see, well, that’s just like you, Kousuke.”

Risako showed an exasperated expression.

“Well, never mind. From here on out, let me speak as Kousuke’s childhood friend. Is Nishimiya Rwn your real elder sister?”
