The Daily Life of the Cat-Like Sister and Her Foolish Elder Brother

[Really? You don’t have any plans for Christmas, Yayoi?]

“Well, everywhere will be crowded, right? I’m not good with crowds.”

[That’s surprising… I thought you’d be going on a date with Tsukasa-san…]

“…Misaki, it seems like you’re misunderstanding something. Tsukasa and I are siblings, you know? Why would siblings go on a date?”

Honestly, Misaki was also quite a handful… Oh, this spot looks nice. The illumination is beautiful.

So, Christmas dinner, huh? I wonder if we can get a reservation at this point?

[Oh, in that case… how about joining us for drinks? A group of us loners will be gathering from the 24th to the 25th. We won’t make you drink like last time!]

“…I’m sorry about that time. I think I’ll refrain from drinking for a while. I got scolded by my brother too.”

[I see… but let’s drink together again sometime!]

“Yes, thank you… Well, I should hang up now. See you at school.”

[Yeah, see you later!]

I set aside my phone and glanced at the magazine.

Hmm-mmh… Where should we go?

“–It looks like the conversation is progressing with the premise of going somewhere, but I’m don’t plan to.”

“Huh, why not?! It’s Christmas, you know! With such a cute little sister like me, not taking me out would defy the laws of the universe!”

“Well, you see… You were the one who insisted on making reservations for dinner and wine because you said you didn’t want to deal with crowds. You were the one throwing a tantrum about wanting a nice room indoors and not wanting to be outside. Oh, and you’re still hung up on that joke from last time… Hey, don’t throw things!”

“B-But you keep bringing it up! …Um, when did I say that? I don’t remember saying anything like that…”

“Oh, really…”

Uh oh… Those were the eyes Tsukasa had whenever he got a little angry.

Overall, Tsukasa was generally sweet, easygoing, and very kind, but when he got mad, it was quite troublesome.

The last time I made him angry, he didn’t talk to me for two whole days until I apologized.

Just thinking about it… What a demon!

Even though I was already at my limit on the first day… He still didn’t want to talk to his cute little sister! Normally, that was the time when the other would be crying and begging for forgiveness!

By the way, I don’t remember how I apologized back then… I said I won’t remember it, and I won’t. Because… it was still a bit… stimulating.

“Why are you red? Don’t tell me that… you’re sick?”

“Huh? Oh, um, well, you see…”

“Hmm… you don’t seem to have a fever. Anyway, we’re not going anywhere this year. That’s settled. I’ve already booked a tree.”

“…It’s unfair to suddenly touch me like that. I need to mentally prepare too, you know! Hey, don’t make decisions on your own.”

“But didn’t you decide that two weeks ago?”

“Ugh…”

What… what was I doing?! Two weeks ago, me?!

Oh no, that was the day I drank with Tsukasa… We didn’t usually drink much, but we opened the wine we got from our sister as a gift… And I don’t remember anything after that.

Apparently, I just hugged Tsukasa and slept like usual, and I didn’t even get a hangover, so I didn’t think much of it until now… And he didn’t say anything either.

…Huh? Wait, could this be really bad?

“Um… Tsukasa…”

“Yeah?”

“Did I… say anything that day?”

“…You want me to say it?”

“Wait! Um… maybe I shouldn’t ask after all. Haha, never mind.”

“I can’t say it, but… if you want proof, there’s a video.”

“What?! Hey!”

“Watch out! …Geez, you’re such a reckless sister!”

“Why on earth were you filming that!?”

“Well, you told me to… you said, ‘Evidence! Evidence is important and necessary!'”

“Ugh…”

My past self is cornering me…

For a moment, I caught a glimpse of it… me, drunk and acting all clingy. And, of course, on his lap.

…This situation might be more serious than I thought. My internal alarm has been going off non-stop.

Oh no, in that state, I wouldn’t even know what I said! It’s like unlocking multiple layers of deep-seated desires, wishes, and all sorts of other things I usually keep locked away in the depths of my heart, and just spewing them out all at once!

Ah… so that’s why I felt so great the next day! Even though I’m not good with alcohol, I drank so much and felt fine, which seemed weird.

I see, I see. It must be because I let out everything I usually can’t say, right? Hmm, I guess that clears up my doubts…

Now, what should I do?

Should I endure the embarrassment and watch the video?

Even if it’s just for a moment, I’m already under considerable mental strain, right?

Should I ask Tsukasa… but, um, that’s, uh, more like…?

But what if… what if I don’t know how to handle things after finding out?!

Considering my personality, I’m not confident that I won’t go off the rails after hearing it. Or rather… attack. I’ll attack and make it a non-issue.

Anyway, what I do know is… we’re spending Christmas at home, and we’ve got the cooking, wine, and the tree ready, right?

So, what’s left is…

“Oh, come to think of it…”

“! W-What now!?”
