偷偷在草稿纸上写下你名字
[tōu tōu zài căo găo zhĭ shàng xiĕ xià nĭ míng zì]
This translates to 'Secretly writing your name on rough paper.' It describes a very sweet, tender emotion - someone writes the beloved one's name somewhere secret just because thinking of them makes their hearts overflowed with love, even if nobody knows, not even that someone himself might see what was written again.
