Singing love songs with your back

Please don't want me

Look at me, how dare you sing love songs?

However, I want to choose today to reveal my sadness

Please pretend to be stupid after listening

But after singing, the audience was quiet. In fact, passers-by were not stupid.

I'll be tortured for you

If you feel too much tears, sing love songs with your back

Can I see through the back of my head and feel something in my heart?
