我是贱人深爱一个烂人
[wŏ shì jiàn rén shēn ài yī gè làn rén]
Translated as 'I am a despicable person deeply in love with a no-good person.' It shows the owner admitting some kind of inferiority in their character and accepting a troubled or unhealthy attachment. This might be expressing self-disprecation and an infatuation involving personal struggle.
