Staying [Boku No Hero Academia]

Since when did a regular grocery shopping went into a chase for a slime monster villain?
Ayuna was shopping for dinner with Toshinori Yagi, also known as All Might. Normal right?
Just when they were also to exit the store, All Might just had to run after the slime criminal leaving all the groceries to her. By the time Ayuna found him again, All Might was accompanied by a small and weak broccoli.
'Oh fu-,' Ayuna cursed in her mind. "What did you do this time?" she groaned in annoyance, glaring at the two.
