Satoru Gojo found that you were prone to over explain.

Though it contradicted your personality a bit, you'd always find a way to over explain, or apologize when not needed, even if in a simple mumblance. It took a bit for him to really take not of it; to really start thinking about it, but he did. Whenever he'd ask why you were late to an event, why something was even slightly off about you; you'd always tell him just a bit too much. He didn't mind it at all; quite the opposite. But he wanted to know why you did it. He was sure you had a reason.

Today was one of those circumstances. You'd had a mission during the evening prior, so you'd been gone almost all night. He was unaware of your mission, so when he hadn't seen you in the students dormitory that night he'd gotten a little curious. So naturally, during training around midday, he asked you where you'd went, and you began.

Apology. Long explanation. It was all the same.

Finally, he stifled a sigh and cut you off, tugging at his collar absentmindedly.

"Why do you always do that?" It sounded maybe a little ruder than he'd intended, as he hadn't intended it to sound rude at all.
