Needing you by my side NaLu

Lisanna is back and Lucy feels left out so she decides to go on a solo mission. It turns out not being a mission but she get's offered to become a student to one powerful celestial mage, but there is a catch. She has to leave the guild for some time. Do she dare leave Natsu alone with Lisanna that she is sure of has feelings for Natsu just like Lucy do. And what new enemies might she have gotten on her time away from the guild?

This is set before the time skip and the battle with Zeref's demons but after the seven year time skip. I will have my own time skip in the fic.
