To keep you safe
I'd follow you to heaven (Go into space fixing the engine)
and forsake myself to the fiery pit along the way. (Die from the heat)
To keep me safe
you threw it all away. (Abort the mission to save Shera)
My bonds were sealed with this act. (Now Shera feels she has to stay with Cid)
I'll follow you forever
from hades and back (Pretty much till death do us part for better or worse)
'til the day your wings return. (Cid finally gets his dream)
So Cid and Shera's relationship.
