Lyrics:

Chinese version:

You don’t understand people like me, you don’t know anything

If anyone has ever loved you, you will understand me

There is no way I can become you, nor can I exchange our hearts

As long as you continue to love like this, you You will understand how I feel, right?

This is the first time that I want to protect another person’s heart like this

You don’t understand, right?

I’m looking forward to it Okay, it’s really hard, it’s really been a long wait

It really took a long time to get here

This is not a coincidence, it’s mine My heart knows you first

I have been waiting for you for a long time, and I said these words

Love will change many things

Even some I thought would not change My little habits have also changed

I hope that the last person will be you, the person who can marry me

That person, I hope it will be you

It’s okay to look forward to it, it’s really hard, it’s really been a long wait

It really took a long time to get here

Isn’t this a coincidence? , it was my heart that knew you first

I have been waiting for you for a long time, and I said these words, from a long time ago, this is love

Love me, you face me Shouting at the world

Let me protect you now

Even if my body changes, my heart will still be here

Because it is My heart got to know you first
