I know you want to go home...

(Please...not again!
Don't break my heart!!...)

But i can't stand being alone
I just can't give up on my dreams

(Is it how it ends?
Should i let you go?)

The underground is so wild...
LET ME PROTECT YOU MY CHILD! 
From what lies behind the ancient doors
Spare my poor heart 
From the pain i felt once before 
For thy understanding i implore

(I must go back
I don't belong here!
You don't understand...
I can't stay here toriel!
This is not right!)

Sorry but i just can't stay
There's no other way
I will be okay
It can't be delayed
I must go away
So let me follow my own headway 

Your past 
It's [bad word] chain
Inflicting you pain
You're letting it drain
Your feelings in vain
Revealing all the earlier
Bloodstains

So we must both say goodbye
And erase each other from our minds
Leaving behind 
All the tears that we kept confined (In a past that no one will find)
Let reality be our guide
As our souls are being purified
