Anyway, we took our seats, each of us ordered a drink, and when it arrived we started talking.

“Yuuki Nii,  can you tell me about your 3 day trip?”

“Um, do I have to tell you everything?”

“Of course.”

I think she would find out even if I hid it from her, so since I’ve to say everything, supposedly, I have to tell her about my sister and Natsuki.

“Well, on the first day, we just played in the ocean like normal.”

“Hmm. ……I’m sure that’s not all, right?”

“Ah, yeah. ……I took a bath with Natsuki and Nee chan, and we went to bed together.”

“Natsuki… Shiori Nee told me about that.”

“I-I see.”

I’m glad that there was less of a reaction here than I thought it would be.

I hadn’t told her about Natsuki, but she seemed to have heard about her from my sister.

But even when I said “with Natsuki,” I didn’t get any reaction from her.

Well, the problem was the second day.

“So, on the second day, we went to an amusement park.”

‘Did anything happen there?”

“Ah, remember Otori kun? I saw him having an affair with a married woman.”

“That scumbag, he can’t be helped anymore… I mean, you have to stop calling him with ‘kun’, Yuuki Nii.”

“I-I see. I’ll be careful.”

Riko was half stunned and half angry.

Even though Riko got angry, she wasn’t disgusted by me, I guess Otori really can’t be helped anymore.

“And then, um……Nee chanand Natsuki confessed to me.”

“Huh !? ….Shiori Nee, she’s getting the head start. And that Natsuki girl….” 

“R-Riko? Are you okay?”

“I’m fine. Yuuki Nii.”

Well of course you’d be surprised.

I had never been popular at all, but suddenly two people confessed their feelings for me.

One of them is my step sister.

“Other than that, nothing special happened, including the third day…I think.”

“I see…hey, Yuuki Nii.”

“What is it?”

“Am I pretty?”

I don’t know how that question came out, but I think Riko is pretty enough in my opinion, so I’m going to be honest and tell her that.

“Of course Riko is pretty. Just by looking at your appearance, I think you’re as cute as your big sister.”

“Really? Fufu, thank you.”

“Oh…this is the first time I’ve seen you smile in a long time. I like it better when you’re smiling, Riko. “

“Really? Then I will do so.”

I’ve never seen Riko so honest or softer.

Until a while ago, we couldn’t even speak to each other.

If I keep on praising her, will we become much like before.

“Yeah, yeah. Riko is good at taking care of others, and a good cook. I’m proud of my beloved little sister.”

“I see. …..Little, sister, huh.”

Hm? I intended to praise her, but for some reason, Riko is feeling down.

It’s not like she’s embarrassed by it, I wonder if I said something wrong.

“Hey, Yuuki Nii.”

“What’s wrong?”

“Do you think of me only as your little sister?”

“Well, I guess so. I still feel like you’re my little sister.”

“I see……hey, can you stay at home tomorrow? Well, I’ll be home tomorrow for a while.”

“Eh? Well, I don’t mind. Do you need help with homework?”

“No. It’s because I found something I have to do to make Yuuki Nii understand.”

No, what? I’m scared.

I’m not sure if I need to be able to understand.

After saying that much, Riko got up from her seat and said that she was going to leave.

There was a couples discount on the bill, but it was still a bit expensive and made my wallet a little bit empty.

My sister had been paying this much money for nothing the other day, so I wondered how much money she had.

After we left the cafe, we picked out some clothes for Riko and went straight home.
