Classmate, Has Your Monthly Mage Arrived Yet?

Researcher Xiang Jin, who worked herself to death from overtime in the lab, transmigrates to a world of magic overnight...

Xiang Jin:

Why do we still have to do research when magic already exists?!

What? I can use magic?

Hehehe...

Why does this thing come around once a month too?! And last a whole week!

This intense sense of deja vu can't just be my imagination, can it???

Hey, classmate, has your magic period come this month?
