It's "Happy Birthday" by Yi Nengjing
Lyrics:
What a simple sentence
Happy Birthday
What an ordinary sentence
Happy Birthday
From childhood to growth
How many times have people said it
At this moment
I just want to say to you
Take the gift for you
Happy Birthday
Music that you can dance to Box
Happy Birthday
From ignorance to growing up
I don’t know how many times I have changed dance partners
At this moment
I just hope it will be you
The music box I gave you
I bought it last year
Leaked music
It’s a song that you and I are both familiar with
Happy Birthday to You
Happy Birthday to You
I always stand in the corner and look at you quietly
Imagine giving you a gift
What will your mood and expression be
Whether you are happy
What a simple sentence
< p>Happy BirthdayWhat an ordinary sentence
Happy Birthday
From childhood to growth
How many times have people said it< /p>
At this moment
I just want to say to you
Take the gift for you
Happy Birthday
A music box that can be danced to
Happy Birthday
From ignorance to growing up
I don’t know how many times I have changed dance partners
< p>At this momentI just hope it will be you
I always stand in the corner quietly looking at you
Imagine giving you a gift< /p>
What mood and expression will you have?
Whether you are happy
I never want to truly have you alone
I also know that you never care
I just want to see your smiling expression
Silence is how I feel about you
