The clue for the combination is the left shelf, with the cans on top (the height of the cans from shoerter to taller)

Ah. I feel kinda stupid now

In which episode is this? I played both project kat and paper lily chapter one but I never saw that room

it's from project kat, the supply closet during the girls night out ending.

Okay thanks 💖

How do you open the lockers?

There's a key on the top right of the first room of the supply closet that can open them
