My name is Isuzu Takashi. I'm forty-nine years old and single.

I recently lost my job, and for that reason, I've continued living as a recluse without even searching for new work. Then one day, I had a visitor at my house. The visitor was a woman dressed in mourning attire: Kamata Shiho, my senior from elementary and junior high school. When she was young, Shiho used to be a kindergarten teacher, but...

Shiho told me she was about to go to the funeral service for someone who had been her senior back in her kindergarten teacher days. However, she came to confirm with me before the funeral, thinking that the deceased senior might be a teacher I knew.

But the deceased teacher's name was 'Yamamoto Kaori'... Even after hearing the name, I didn't remember her. However, just as Shiho was about to leave, the moment she mentioned the senior's maiden name, a shock ran through my body.

Maiden name: "Tsuneya Kaori"...

Tsuneya... T-T-Tsune-chan!! Not *that* 'Tsune-chan'!

The deceased senior—she was none other than the person I had loved, the one who had taken care of me the most: Teacher 'Tsuneya Kaori'.

From that moment, memories of 'Tsune-chan' came flooding back one after another. And then I realized: 'Tsune-chan' was my first love...

As soon as I realized this, I regretted never having met 'Tsune-chan' once since graduating from kindergarten. Why didn't I ever meet 'Tsune-chan', whom I loved so much!? If I had met her... If we had stayed in touch... If I had cherished her more... If I had married 'Tsune-chan'... I wanted to make 'Tsune-chan' happy...

The next day, I, who had recently been plagued by frequent headaches, experienced the most intense pain I had ever felt!! The pain was so excruciating that I burrowed into my futon and closed my eyes, but as the pain gradually subsided, I slowly opened them... The moment I opened my eyes, a somewhat nostalgic scene appeared before me.

Why am I on a train platform when I should be in my room!? My mother is taller than me, and she looks younger. Were my hands ever this small? A-And... w-why is 'Tsune-chan' standing right in front of me!?

Is this a dream? Or...

This is NOV's first time-travel and pure romance novel.

We hope you'll read it all the way to the final chapter.

It's sure to bring tears of emotion, isn't it?

Thank you for your kind consideration.
