Translate with google

Friend of the Heart (Love hearts)

When I was able to release the pain from your heart
My spirits were exploded on the path of life
Prior to meeting you, I wandered lonely
Let me feel the warmth of your fingers

Love always sing a lullaby
When we are tired on the way
Remember me as a love heart

Even the heart of mutual trust has been forgotten somewhere
Why do people pursue happiness that passed away
Close your eyes and slowly reveal your heart’s window
Hold my hand and wipe your tears

Love always sing a lullaby
When we are tired on the way
Remember me as a love heart

that's very nice but sad
