怎么看自己都配不上你
[zĕn me kàn zì jĭ dōu pèi bù shàng nĭ]
Expressing low self-esteem in comparison to the beloved one, this phrase means 'No matter how I look at it, I don't deserve you'. This could stem from deep love combined with inferiority complex, where one doubts if they are adequate for their partner.
