It's Called Surviving [Nalu]

Life for Lucy Heartfillia changed when her mother died when she was a little girl. Her entire world was uprooted and unfortunately so was her father's, Jude Heartfillia.
Now in high school, Lucy has to hide behind stockings and long sleeve shirts to cover up what her friends aren't supposed to see. People believe she is just a shy girl that has an excessive amount of clumsiness and is scared easily. In reality, there is much more that is unexplained and puzzles her dear friends.
Keeping secrets and hiding behind fake smiles is what Lucy calls surviving, but is it really?
Can Natsu and the gang figure out a way to help her or she already what she thinks she is, a lost cause.
