What is a secret love?
It was his girl who secretly hid the paper moon he folded for five years.
It was because I didn't dare to look into his eyes when I saw him.
It was the sadness she felt when she learned that he had a girlfriend.
And when he knew,
She has been keeping this secret for five years.
She had hidden the paper moon for five years.
Intention: She has been hiding that moon in her heart for nine years.
