Night has arrived when I relax myself on my bed after a nice shower. Checking my schedule to see if there's a task due for tomorrow, I realized that tomorrow is Sunday which means a much needed rest for me. Tomorrow I won't go anywhere. I'm tired, and besides, Sunday means that Riku is also home. I can dote as much as I want tomorrow. No, I'm not a brocon.

My phone then rings. The voice of Leo Ieiri singing ripe reaches my ears. I picked my phone and see Hyoudou's name. I pressed the call button to answer it.

"What?"

I think he's going to shout that he did it.

"I did iiiiitttt!"

I'm correct. I'm a psychic now.

"We were walking around and talking and then there were laughs and then I did something stupid and then she smiled and then… and then… Tomorrow we're going on a date!"

I'm wrong. I thought Hyoudou with all his perversion had forced himself on her.

"Congratulations. You're moving past your pathetic self now. Say goodbye to him. Why are you telling me this?"

"I need advice for tomorrow's date."

Hm, what should I tell him? I search for my magazine that host some dating tips. Not that I have any intention for dating or others, I just buy it once or twice because my female friends recommended it to me. It's just a coincidence that there are some articles about tips on dating from the female part. I think that by reading through it and deconstructing what's written there, I can tell some things for Hyoudou.

"Wait for my text. But don't just rely on me. Try searching it yourself."

After that, I ended the call and begins reading on the magazines.

Hmm, it seems that for whatever reason, every female has to wear a nice, preferably new, and matching clothes on date. They have to put on the most sweet-smelling perfume. They also have to arrive late on the date, and then asking their date partners if they were late. Huh? It doesn't make any sense. If you're late, then you need to apologize. What kind of dumb idiot doesn't even realize that they were late.

And then, on the date, they have to let their partners takes charge while linking their arms towards their partners' and rest their heads on their partners' shoulder. No way I'd do something like this. When I was on a not-date with my beloved little brother, I'm the one leading the walk. No way I would let some idiot boys taking charge.

After the date, they have to say that it was a nice date, even if it's a terrible date. Why? It doesn't make sense. If the date's terrible, then just say it so the next date would be better.

I end up throwing the magazine away because it's stupid.

I forget that my objective is to deconstruct it and tell it to Hyoudou. Hehe. I picks my magazine and writes the important points before I deconstructs it.

Some points are valid, such as the nice matching clothes. Hyoudou has to wear that kind of clothes. Then, Hyoudou has to arrive first one hour earlier just to be safe, and let his girlfriend apologize if she's late.

On the date, Hyoudou has to takes charge on where they go, but if she wants to go somewhere, he should let her. I don't know what kind of girl Hyoudou girlfriend is, after all. If she's kind of agitated, Hyoudou should try to take her hand to calm her. That was what I did to calm my brother.

After the date, Hyoudou has to thank her for the nice date, and pour his thought if he thinks the date is terrible.

Yes, this should do it.

I send the points I've made to Hyoudou. I also said that I expects the after-date report and if he needs me, just text me because I won't be going anywhere tomorrow. Seconds later, the reply comes.

Thanks, 'Nee-san'.

I closes my phone, put it on the desk, then I turns off the light before I lay myself on my bed.

No fucking way.

There's no fucking way Hyoudou's the one who sent that message.

Please don't make Hyoudou's the sender.

As I hug my pillow, trying to sleep, my mind is cannot be taken from the message Hyoudou sent.

On that night, Hyoudou Issei unknowingly became the second person who manages to trigger my big sister switch.

I don't know how to face him on Monday.

The next morning comes quietly. One glance at my phone reveals that Hyoudou did not contact me. I can imagine how nervous he is. This is his first date, after all. I would be nervous too if I'm on my first date. I just hope he won't do something stupid. I shake my head. Why the hell is he the first thing I thought in the morning? No no. There's something much more important than him. Like, the Super Hero Time in the morning with Riku. I check the time. Oh! It's already the time!

"Onee-chan! Come!"

Riku barges into my room enthusiastically.

"Of course, Riku. Just wait for a bit. Turns on the television, would you?"

I tidy up my bed first, it's a good habit that has been ingrained in my mind from my childhood. After the room is clean, I go to Riku's room and tidy it up for him. Riku has this cute adorable habit of not tidying up his bed. Of course after that I searches for suspicious things. Riku is pure, he shouldn't have suspicious things.

The Super Hero Time passes quickly. Seeing Riku's adorable face at some scene makes my heart warm. Oh Riku! You're the cutest thing ever.

After that, Riku demands for breakfast cutely, imitating the villain from the tokusatsu show, I don't remember the name, but Riku thinks the villain is cool so he must be cool.

My parents worked overtime last night, so I can understand that they are tired. I wish they can accompany Riku though. I feel that Riku lacks the love of our parents. Well, not that it's important since my love makes up for my parents'.

As I laugh together with Riku, I can't help but glance at my phone. One check confirmed that Hyoudou hasn't contacted me yet. It's still morning. What time is the date start again? Afternoon? Or morning? I forget what Hyoudou told me, that makes me hesitate to call him. Getting a call from a girl when he's on a date would reflects bad at him.

I stopped myself from continuing that train of thought.

Since when did I care about his date?

Yesterday, I didn't care for his reputation. I also didn't care about his date's opinion, and told him to be himself.

I fiddle with my phone, checking the messages. My phone displays the last message he sent.

Thanks, 'Nee-san'.

I feel something warm on my heart. Hyoudou truly did trigger my big sister switch. I hope he's alright. May his date be the perfect date.

I think he's too nervous to contact me. Maybe this time, I need to be the one texting him first. That way, even if he's on the date, his date won't feel annoyed or something.

Good luck.

I get the confirmation that my messages have been sent. With a smile, I close my phone.

"He doesn't contact me."

Worrying about Hyoudou, I end up spending my time inside my room, with my phone in my grip. And yet, even when the moon has shown himself up in the sparkling night sky, he doesn't contact me at all! That actually makes me a little upset. I asked him nicely to tell me about the date, and he doesn't contact me at all.

Well, two can play at that game. I won't reply any of your text, or pick up any of your call either!

God. My life's better when I don't know Hyoudou. Why the hell does he need to triggers my big sister switch?! Now I care about he and his date! Curse you, Hyoudou! You stupid stupid stupid idiooooootttt!

Wait.

Don't tell me.

Don't tell me he's enjoying the night with her date.

Goddamn, Hyoudou can't withhold his urges.

Well, even if it's unlikely, the latter is more possible if I consider Hyoudou. Maybe once again, I'm being harsh with him. Yes, not replying or picking up the phone is too harsh.

Tomorrow I'm going to meet him, after all. And I am confident I can read his body language.
