你的爱是我吸进肺里的烟
[nĭ de ài shì wŏ xī jìn fèi lĭ de yān]
'Your love is the smoke I inhale into my lungs.' It is a metaphorical expression where 'love' can cause a sense similar to smoking: it is intoxicating and even though harmful (addictive), it can give pleasure for a moment, yet also leaves the person breathless, indicating a painful yet intense experience associated with this specific kind of love.
