Inko is going on a date with Toshi, but she’s freaking out about her hair, and Izuku knows exactly -.05% about styling hair, and both are freaking out until Izuku remembers that OH YEAH KACCHAN KNOWS HOW TO STYLE HAIR
so Izuku calls Bakugou all frantic-like–it goes something like this
Izuku: KACCHAN COULD YOU COME OVER TO MY HOUSE REALLY QUICK??
Bakugou: WHAT THE FUCK WHY
Izuku: MY MOM’S GOING ON A DATE WITH ALL MIGHT–
Izuku: –AND NEITHER OF US KNOW HOW TO STYLE HER HAIR RIGHT–
Izuku: –SO COULD YOU PLEASE HELP US KACCHAN????
Bakugou: I’M ON MY FUCKING WAY, DEKU
so Bakugou rushes over to Izuku’s house so he can fix up Inko’s hair all super nice and fancy before All Might can arrive
and later on, when All Might does arrive, Bakugou is the one who answer the door. he looks up at Toshi’s unkempt hair for all of three seconds before he’s like “NO. NO FUCKING WAY. YOU ARE NOT GOING ON THIS DATE LOOKING LIKE THAT. NOT AFTER ALL THE WORK I JUST FUCKING DID.” and drags All Might, who is completely baffled (???? why is Bakugou here??? how does he know about his date with Inko????) to the bathroom to fix his hair up b/c jfc someone has to take charge here
and that’s the story of how Bakugou helped All Might and Inko get ready for their date
