A/N: For those who skipped chapters 2 and 3, basically what happened was 8man talked to the girl, and was convinced that she was the young Hiratsuka. He then realized that he may have traveled back in time ten years earlier. Without all the life necessities, he decided to use the school as a shelter, and utilized all that he had on him. When he woke up the next morning, a mysterious lady appeared and gave him all that he needed to survive (documents, money, and shelter), told him to live his life as a teenager, and then disappeared.

"Ah, I'm done with this – I really just can't deal with it any longer", Hiratsuka said, crying and complaining after realizing she couldn't answer the question from the English homework. Not to brag, but it was only the first day that I started going to class, but I've already done all the make up assignments, as well as the assignments given to me for the day. She, however, struggled to even finish one of hers.

'Is this is girl really becoming a teacher?!'

"Hikigaya-kun, you're finished with your work right?", she asked. Damn, at the moment I knew she was going to ask me for help. What sucked was the fact that she probably knew I'll never reject her request.

"Yeah"

"Can you help me with the last question, please?"

Nailed it. Man, why couldn't her older counterpart be this kind of whiny? "Hikigaya, join the Service Club, pretty please?" – uh, no I shouldn't had imagined that scenario; it was so weird I had the image burned to my brain. What the heck was I thinking?

"Ok, let's see: ["I don't have the BLANK amount of money in my bank account, so I'll go deposit.", which of these word is the most appropriate to fill in the blank: Atoned, Adequate, Appreciated, or Atrocious?]"

'Is it just me or this worksheet is trying to mock me? Did the mysterious women I met earlier write this?'

"'Adequate' is the answer"

Of course, being the first day of school, I needed a bit of getting used to, no matter how ironic that may sound. Yes, it's true that I spent a year and a half studying in the same school before being sent back in time, but the difference I felt wasn't from the school building itself, 'it's the people – It's true that I usually don't converse with my classmates, even if it's ten years later, but having different sets of them can make you feel foreign. Their impression of me was no different from ones of those in the future, which surprisingly, is indifferent. From this point, it's just a matter of whether or not I will make them resent me. Other than that, I also feel like something is missing: the usual gathering called Service Club; the usual 'ya hallo!' phrase Yuigahama will yell every time she sees Yukinoshita, who might just either be reading a book, or in the process of making tea. Sometimes, the club activities will be interrupted by Hirats- uh, well, she's here, technically'

"Hikigaya-kun", said Hiratsuka, rotating herself toward my seat, and rested her arms on top of the wooden backrest.

"I created a club"

""And I need members, or else it gets disbanded", correct?"

"Yep, you catch on quick"

"What are you? Some club members hunter who at first act helpless and act close to the prospect, then when they actually join you don't talk to them at all whatsoever?"

'Yes, there are people out there who will act all friendly to you just to let you join their club – basically using you as a human filler, and nothing else. In reality, those people might not even want to get in the ten meters radius of you. Source: Me'

"Why do you have to be so cynical, Hikigaya-kun? I don't just recruit random members, you know?"

'Ah, that makes me feel a little special'

"Fine, I guess. What club is it?"

"Service Club"

'No'

"Huh?! Uh, I mean.. what do you do in this "Service Club"?"

"Quite simple: we help those who want help"

'Uh, no, this has to be some sort of coincidence, isn't it?'

"Hikigaya-kun, you do not hesitate to help those in need, as seen yesterday when you helped me; that trait of you makes you a perfect candidate for a member!"

"I thought it's to punish those who have different views of adolescence?!".

"Huh, what do you mean by that?"

"Uh, no, nothing – forget what I said. I'll join"

"Great, follow me"

It should be no surprise to me by now, but she seemed to have retained her "forceful" personality well into her late twenties. We took some distance walk from the classroom, but the club room is still nowhere in sight. After we went up the stairs, however, things seemed to make more sense to me; we went through the corridor that Yuigahama and I usually go through. At the time, the stairs which I usually took didn't exists then, which means I had to walk the extra distance to get to the other stairs that will lead to the corridor. Up ahead was another corridor that goes horizontally to the one I was walking in, and in the center, there was a room, one that I was sure of its purpose.

"This is the Service Club room", said Hiratsuka. She then slid the door open, and we both entered the room. With the first step, I immediately caught a very familiar scent – it was grassy, yet very appealing to the nostrils. It reminded me of the usual: It was the green tea. It smelled exactly like the one Yukinoshita usually make.

"I see. It's no different from ten years later", I said, and then smiled subconsciously at the thought.

"What are you talking about?"

I shouldn't have said that.

"Uh, no.. I just.."

"You just like to say weird stuff like that. Are you some guy in the future who got sent back in time or something?"

'Again, how the heck can she be this spot on?'

"Like I said, that sort of thing isn't possible", I said, being able to regain composure.

"I see. Well, anyway, you're the first person in school besides me to ever join this club, which means the Service Club is now officially open!", she said, then pointed at my direction.

"Hikigaya-kun, from tomorrow onward, we'll start the club activities."

Wow, that enthusiasm; it was the opposite reaction to that of Yukinoshita when I first joined the Service Club, I knew that much. I did realize something about it, however, that there's a lot more to its history. Ten years later, something probably reminded her of the Service Club, and then she decided to create it again to relive her youth, probably. What I didn't know yet, however, was if Hiratsuka will be the one who starts the whole thing, then how Yukinoshita will be related to it at all.

I separated from Hiratsuka as soon as little bit we decided on our agenda the next day, which was to go around and stick the club poster to promote the club activity.

It was a good time to check on the place rented for me by the lady. It wasn't far from the school, being only two stations away. It was your typical apartment, having a living room, a bedroom, a bathroom, and a kitchen – it wasn't as luxurious as Yukinoshita's place, but I was more than satisfied with what I got. I said it myself, didn't I? "food tastes best when you do not have to work for it".

"Ah, right, I didn't get to sleep well last night", I said as I plopped myself onto the bed, realizing the fact just when exhaustion kicked in suddenly. I then slowly closed my eyes, granting the wish of the pair that desperately wanted their share of rest.

"I wonder what they are up to"

"Hello? Ah, Komachi-chan, what's up?"

"Hikki? No, Hikki has not been to school for two days straight"

"I couldn't get hold of him either – is he alright?"

"Huh, he wasn't home either?!"

"Yeah, I got it. I'll call Yukinon, then I'll call the police as well, okay?"

"Alright, I'll do what I can. See you, Komachi-chan"

"Hikki.."

"Good work, Hikigaya-kun", said Hiratsuka, applauding me for already having the poster sticking done in half an hour time. We have them pasted all over the school where people might see them. It wasn't really that hard of a work, but I sure was worn out from it, probably because we had to chase the people who thought these are supposed to be torn off the wall. If they were supposed to be handed out, then I would've handed them out – I don't understand what was so hard about it.

"At least everything's done"

"Yeah, let's go home"

I nodded as a reply, and decided to start walking. When I was about to lift my foot up for the first step, however, something struck me in the leg so hard, I fell to the ground. That something fell down as well, and landed on my back in the prone position. It wasn't as heavy as a sandbag, and it wasn't as light as a pillow, either, but it's weight was enough to keep me pinned on the ground.

"I'm sorry, Nii-san. Are you hurt?", said that something – it sounded like a little girl, so like some obsessed lollicon, I assumed that it was a little girl. Oh, how Isshiki was right about that.

"Don't worry about it, just please, get off me"

'Yes, as I thought, it's a little girl. Who would've thought?'.

She had black bobbed hair that was well conditioned, even running through the cold doesn't seemed to have affected the quality of its spreaded ends. She had eyes whose color was somewhere in the lower center of the Planckian locus. If anything, they felt neutral, neither cold or warm; it was as if she had yet to experience emotions at any end of the temperature spectrum.

"I'm sorry, I was in a hurry", she said.

"Where are you going?", Hiratsuka asked, lowering her knees, making her self the same height as the girl.

"My sister ran away from home", the girl said, looking at the ground and fidgeting her hair. She was a surprisingly shy girl.

"Oh, so you came looking for her"

"You're such a nice sister. I know! Why don't we help you find her?"

"That's great, Nee-san!"

I had never seen Hiratsuka-sensei act like some Nee-san [1] before (she'd be an Oba-san [2] by then. Don't ever tell her I said that), not even close to this. Man, something must've really happened in the next ten years time.

"What does she looks like?"

"Hmm.. her looks? Let's see.. she is a little shorter than me"

"Her hair is longer than mine", the girl said, doing a hand gesture on her waist that indicated the length of her sister's hair.

"Ah, if you want to call her, her name is Yukino"

'Huh?!'

[1] – What you refer to some lady who is older than you. Although, a really old lady will be happy if you call her that, other people might look at you weirdly.

[2] – What you would refer to some old lady. Don't use this to address any lady in their twenties if you do not wish to be slapped.

A/N: There you go, for those who wanted longer chapters.
