Shintaro's Theory of Happiness

Prologue

Shintaro's p.o.v

Again those years run on by…

I felt my eyes widened as I saw the picture that had caught my attention when I went to wake up the sleeping fluff ball known as Mary.

The picture held an antagonizing memory that I could never forget. Her face stuck in a permanent smile, just the way I remember her. She even wore her signature red scarf that contrasted starkly with her black uniform and pale skin.

Ayano…

I had unconsciously picked up the picture frame and I had only realized that I had when the frame slipped from my fingers and had come crashing to the ground, sending glass everywhere and immediately waking up the person I had initially come for.

"Shintaro," Mary questioned, "What's wrong? What happened?"

"Why is Ayano standing with the others?" I mumbled out. I didn't care if she knew what I was talking about; I was too shocked to care.

She carefully made her way towards me to see that I was talking about the girl in the photo that now lay on the ground, cracked and surrounded by shards of its own glass.

My mind filling up with only family…

"Oh that's the dan's original danchou," she answered "She was also Seto's, Kido's, and Kano's Nee-chan, but she died of suicide a couple of years ago."

When I stayed silent, she continued to babble on.

"I've always wanted to meet her, but every time I reset the timeline, she always ends up dying. It makes me sad when I find out I can't meet her. She must have been a great danchou by the way the others talk about her."

At that, I turned toward her sharply and gripped her tight by the shoulders, making her also spin to face me, and asked,

"You can reset time?"

Her eyes widened as she realized that she said something she shouldn't have. When I shook her shoulders for extra measure, she tentatively nodded her head.

That was it! I'd have Mary reset the time and I could save Ayano! Everybody would be happy. Everything would be okay.

"Mary please, you have to send us back in time to two years ago."

"I-I don't think that I should, Shintaro. What if something goes wrong? What if I get left behind? I don't want to stay in those woods forever!"

"Mary, Mary, please? I won't let that happen. I'll come get you the second I get Ayano and you can meet her and be with everyone else again. Doesn't that seem nice?"

She looked conflicted at what I was saying before asking,

"C-could you have Seto come get me? I don't want to change the way we meet."

"Alright, I'll have Seto come get you right when I see him." Again, she hesitated before nodding her head and saying,

"Okay, I'll reset time to two years ago this day. You and I will be the only ones who remember, so you have to promise you'll do that."

"I promise."

I actually had no clue how it was all going to turn out, but I would promise anything if it meant that I got the chance to save Ayano. I had to succeed, no matter the cost.

Mary then gripped my hands and the last thing I saw was her glowing, red eyes.

Ayano now's your big sister everyone, so try to get along with her for me please.
