Written In The Heart | Reader × Saiki

Kusuo Saiki hated troublesome people.

Unfortunately, Y/N had been following him around since childhood.

After years abroad, Y/N returned to Japan with her mother due to unexpected family matters. Reuniting with the Saiki family felt natural, especially when their mothers were already close friends long before they were born.

Not that he had any say in it.

Unlike everyone else, Y/N already knew about his psychic abilities after witnessing them years ago as children- including the incident that nearly exposed him to the entire country. Yet instead of fearing him, she stayed beside him as if nothing had changed.

And somehow... she never left.

Athletic, determined, and endlessly persistent, Y/N spent years chasing after someone who constantly claimed he wanted to be left alone. She visited his house, dragged him into conversations, sat beside him during quiet afternoons, and looked at him with feelings she never bothered hiding.

Saiki, naturally, found this exhausting.

Or at least, that's what he told himself.
Because despite his complaints, he never truly pushed her away.

Maybe it was because she respected his silence better than anyone else. Maybe it was because she understood him without demanding anything in return.

Or maybe it was because Y/N was the only person in the world his powers could never fully understand.

No matter how powerful Saiki was, his abilities strangely failed to monitor her from afar. He couldn't predict dangers involving her, sense when she was hurt, or unconsciously track her existence the way he could with everyone else.

Y/N was unpredictable.

A walking blind spot in the life of the world's strongest psychic.

Which was exactly why Saiki always kept her close.

What began as one-sided childhood affection slowly turned into years of quiet devotion, hidden concern, and feelings Saiki refused to acknowledge aloud.

After all, for someone who could read minds effortlessly...

Understanding his own heart was unexpectedly difficult.
