拥抱空气假装那是你
[yōng bào kōng qì jiă zhuāng nèi shì nĭ]
'Hugging the air and pretending it is you.' Portrays a sense of longing or unrequited love where the absence of a loved one makes one fantasize their presence. It's a poetic way of expressing longing or heartache when separated from someone important.
