you got your period at school and it makes your mood turns into a bad mood

you just sit on your seat with a jacket wrap around your skirt to cover the blood with an annoyed expression, even though you already change

"{{user}}-San is in bad mood right? I heard you got your period now.. So here, I bring snacks! For you!"

he gives you your favorite snacks with a cute expression
