Much to All Might's exasperation!

"WHAT DO YOU MEAN YOU TOLD YOUR MOTHER ABOUT ONE FOR ALL!?" Toshinori shouted into the phone as he sat in his office.

"Ack!" Izuku yelped as he clearly fumbled with the phone on the other end. "...she overheard a few details about it in addition to the genie stuff-"

"I said I was sorry!" Ochaco's voice could be heard in the background.

"...and, well, I kind of told her about the details. I didn't remember how much I had said at the time she referenced eavesdropping in on, so I just decided on full honesty..."

"...that's three times you've been overheard now," Toshinori sighed. "One of them not even having super hearing!"

"...ironically, only the one without the superhearing Quirk knows about both Momo and One for All. Kyoka and Mirko only know about the genie stuff," Izuku remarked.

"Still, before I met you, only three people besides us knew about One for All. Three!" Toshinori groaned. "And yet, in about a year since I knew you, that number has more than tripled, given you told your entire harem, and now your mother. Do you have some kind of Quirk I didn't know about that draws people to your secrets?" Toshinori then sweat dropped as he heard Izuku start to deny it, then pause, and start muttering on the other end on such a Quirk, and how it might work. "...it was a rhetorical question!"

"Ah! Sorry!" Izuku replied sheepishly. "...if it makes you feel better, I wished with Momo that any details about my sex life and any other major secrets a casual eavesdropper might hear would be heard as something more innocuous from now on... should have done that from the beginning, in hindsight..."

"They say hindsight is 20/20, but clearly, your foresight needs glasses," Toshinori deadpanned. "...but at least no one we can't stand to know has overheard you as of yet... still, it's good to know that this won't develop into an actual problem going forward."

"So, you're not mad?"

"...more exasperated than anything," Toshinori sighed. "I should probably pay your mother a visit and clear up any further questions she might have. Speaking of talks, come to my office after classes tomorrow. We need to have a conversation about something else related to our Quirk..."

"Oh, right, understood!" Izuku replied, before hanging up. Toshinori sighed and reclined in his chair.

"...when did my life get so absurd?" he asked no one in particular.
