――My long-distance girlfriend, Umikawa Megumi, cheated on me.

Apparently, the person she cheated with was the most handsome guy in school, excelling in both academics and sports.

―――I was shocked.

But, disliking lingering attachments, I deleted all means of contacting her.

――Several months passed.

Yet, I still spent my days unable to move on from her or forget her.

I thought time would make me forget her.

But deep down, a part of me still didn't want to give up on her.

Sigh... How pathetic and clinging I am.

Then, one day, as these dazed days continued.

―――I was hit by a runaway truck.

As I met my end, wishing that this time I would find a good woman, my eyelids slowly closed as if the curtain of my life was falling.

And the next moment I closed my eyes,

I was forcibly woken up by someone's loud voice.

The owner of that loud voice... a woman who called herself Goddess Meliana, spoke to me.

She wanted me to become a hero and subjugate the demons rampant in her world, as well as their leader, the Demon Lord.

At first, I tried to refuse.

But then, a thought struck me.

"If I become a hero and immerse myself in a mission, won't I be able to forget Megumi!?"

Seeing this as my chance to finally move on from Megumi, I gladly accepted Goddess Meliana's plea and was summoned as a hero to another world.

―――Five years and several months passed.

After overcoming countless hardships and successfully defeating the Demon Lord—Goddess Meliana's earnest wish—I returned to my original world, retaining the power of a 'Hero' as a reward from Meliana.
