she's really been on this theme of lost and rekindled love lately.
some lyrics from her latest nightcore song:

"When I think about you
My feelings can't explain
Why after all this time
My heart still feels pain

When I look at you
Memories of love
Like no one before
You stay on my mind
(Special feelings, special time)
Always so special
(I was yours and you were mine)
Made for each other
(All the good I won't forget)
