They Say My Past Life Was the Lover of an S-Rank Esper

An ordinary civilian woman, Yu Yeon, suddenly has a man appear before her.

The man is Ryu Siho, an S-rank esper—someone she should never have crossed paths with even once in her life—and she is only bewildered by his appearance.

"Seo Haena? Esper? Who is that?"

"You."

"Pardon?"

But somehow, the person who came looking for her had even gotten the name wrong from the start.

After briefly sneering at his nonsense, Yu Yeon follows the man and ends up recalling a dizzying memory.

["...Haena, Seo Haena."]

'What is this? I never did that!'

From that day on,

Yu Yeon awakens as a guide and joins the Esper Management Bureau. On top of that, she is abruptly paired as a temporary partner with a high-ranking esper whose match rate is 93%.

When she looks to see who the other person is...

"You’re here?"

It is that man.

"There was a 'big incident' between us. I want to know what you were thinking back then."

"You said you’d come back and tell me everything. You promised. I waited quietly, I did. And then you never came back."

"...Did it not matter if I died?"

...What exactly was the relationship between this person and me?
