I found the lyrics of the song here: Les paroles de la chanson: Ne m’oublie pas, du film Coco.
And although it's relatively simple, I am struggling a bit to understand the grammar point of the 2 sentences:
- Je vais devoir m’en aller.
- Pour que tu n’aies plus peur.
I am not sure which part of the full sentence “en” is supposed to replace and is “m'” the short form of “me”? If yes then what does “me aller” mean?
Why is avoir conjugated as “aie” in the second sentence?
