Andromediaen, Not Angel (Seventeen Fanfic)

RiRi is what humans would call an angel. But that's not very accurate. RiRi and her fellow 'angels' are not sent from heaven. Instead, they come from Pearlencse, a planet in the galaxy of Andromeda. These creatures' purpose is to protect certain chosen individuals on Earth. RiRi, however, is given the special assignment to look over not one, but thirteen boys in the small area that she learns is called Korea.

Everyday, RiRi spends her time watching over these boys, and exploring the Earthly amusements that she finds as she follows the chosen 13. One day, however, everything goes terribly wrong, and RiRi must put her gathered knowledge of Earthlings to the test in order to go back home without anyone's notice. But can she navigate her way through the perils of every teenager's fear-high school?

Loosely based off of the drama Hi! School Love On.
