Inko and her son were having a conversation one day.

”I got my first boyfriend when i was 18. So honey, no girls until you're 18.” Inko said seriously, to which Izuku only responded with a bored shrug.

One week later,this Sunday, Katsuki and Izuku were making out in Izuku's room,and were too distracted to hear Inko's approaching footsteps.

”Izuku is everything fin—” Inko didn't get to finish her sentence at the sight in front of her.

There was Katsuki, with messy hair, wearing his usual tank-top and baggy pants, holding a flustered Izuku into a content embrace.

They both froze when they figured Inko saw them.
