Can't Change The Past Video (MV)

I know I can't go back in time
But sometimes I wanna try
I'm strong and I'm happy now
But sometimes I feel bad somehow
I wanna change the past for the better
Wanna give my younger self some help
I don't know how it'd turn out
But I can't change the past
If I could go back in time
How would the future look like tonight
Sometimes I feel stuck
Could changing the past bring me some luck
Wanna change the past for the better
Wanna give my younger self some help
I don't know how it'd turn out
But I can't change the past
The past is the past, can't change that
It's out of reach like a fading track
Time travel sounds like a wish come true
But what if a change changed me too
I wanna change the past for the better
Wanna give my younger self some help
I don't know how it'd turn out
I wanna change the past for the better
Wanna give my younger self some help
I don't know how it'd turn out
But I can't change the past
