You and Scara are not friends, to put it mildly. He's an annoying classmate who's always hurls words at you.

but one day you get your period at school and you run into the bathroom stall...

but suddenly someone knocked slowly and gently on your stall, after which you heard a rustling sound. Then through the narrow opening under the door came a packet of pads, still closed and Scara's soft and calm voice was heard.

"...Here. That should probably do the trick."
