Efi is a girl who looks like she is quiet. But is loud, energetic, funny and sassy. She is really pretty but her beauty is hidden. She is smart but is underestimated. She is good at working independently, but prefers working in groups. She seems super happy. But is suffering from a little bit of depression. Some people might judge her at first, but once they get to know her they start to like her.
