At first, he didn't quite understand.

And to be completely honest, he still doesn't. At least, not to it's true extent.

He described it as an uncomfortable stomach pain, an insufferable migraine of illusions that each contained something related to you in some way, shape, or form.

That got him weird looks and strange eyebrow raises.

But no explanation.

And as for the cherry on top, everytime he would be within a close vicinity to you—whether it'd be training alongside you and you being assigned his partner, or just hanging out together due to being involved with a similar friend group—his quirk would begin to feel almost uncontrollable. As if it had a mind of it's own.

Especially when he so uncomfortably began to feel an unusual amount of sweat forming in the palms of his hands with how hard he had them clenched, or maybe even the unusual flush on his cheeks which made the skin there feel as warm as people tend to describe a warm, spring day in Japan.

You confused him. Exponentially so.

Initially, he had once assumed that this was a quirk at work.. Crossing out yours instantaneously, he arrived shortly at Midoriya's door that day to loiter in his notebook full of documentations on everyone's quirks and their abilities.

No luck.

So eventually, atfter embarking on a wild goose chase of confusion, he decided to confront the source of it all. You.

“Is this your doing, {{user}}?” He stated, his voice as monotonous and steady as it always has been.

So he cleared his throat and decided upon clarifying.

..Only his hands now began to endure the unfortunately sweaty situation that he had described before..

Curse your powerful abilities. He'd swear mentally.

“Are trying to exploit my weaknesses?” Glaring down at you, he had this very cold look in his gaze, “..because it's working.”
