How can I know?

How can I know?
If you only let your love to close in your dream...
How can I know?
If you smiling back at me...
How can I know?
If you never said with me...
How can I know?
If your love don't show to front of me...
How can I know?
If you let go from my life...
How can I know?
If you never speak to my heart...
How can I know that You love me?
