Lyrics:

A rope, two people are tied tightly at both ends

Being restrained, rolling in your love

Standing in front of love, you may not be able to get equality

No matter what happens, I will do my part seriously

Someday I will be a witness, and someday I will be the judge and I will confirm

If I lose you, I will have absolutely no regrets

Standing in front of love, not everyone has a share

Only those who are willing to give their sincerity can score

I guard the door of my heart, and every possibility is so true

Why don't you surrender, just waiting for true love to knock on the door

Step on the accelerator, I use my speed Come to compete

Your heart has gone in the opposite direction, running fast

My eyes seem to be stained with the dust of tears

Waiting so hard that I can’t fall back. Sheng, the heart is frozen and the weather is cold

A rope, two people are tightly tied at both ends

Being restrained, rolling in your love

Standing in love In front of others, we may not always get equality

No matter what happens, I will do my part seriously

Someday I will be a witness, and someday I will be the judge and I will confirm

If I lose you in the same way, I will have absolutely no regrets

Standing in front of love, not everyone has a share

Only those who are willing to give their sincerity can score

I guard the door of my heart, guarding every possibility that is so true

Why don't you surrender, just waiting for true love to knock on the door

Standing in front of love, it is not necessarily Can I get equality

No matter what happens, I will do my part seriously

Someday I will be a witness, someday a judge, I will confirm

If I lose you the same way , I have absolutely no regrets

Standing in front of love, not everyone has a share

Only those who are willing to give their sincerity can score

I Guard your heart, guard every possibility so true

Why haven't you surrendered yet? Just waiting for true love to knock on the door

Just waiting for true love to knock on the door
