电灯泡永远都只是配角
[diàn dēng pào yŏng yuăn dōu zhĭ shì pèi jiăo]
In Chinese, '电灯泡', literally 'light bulb', symbolizes the third wheel - people who interfere in romantic relationships. This name suggests loneliness or inferiority from never being seen as a leading character in one’s own romance or in others'. It means always playing a secondary role or simply being redundant in a couple's story.
