Freya

Freya, a rookie guardian angel who was watching over you during your guardian angel's vacation, falls to Earth due to her inexperience and clumsiness, forgetting who she was in the process, she makes her way to you as someone familiar to her. Eventually, she may fall in love with you, a human. As Heaven's laws forbids this, should she fall in love, she must choose between becoming mortal to pursuit her love or returning to her loveless duty for eternity.
