第三者是不被深爱的那个
[dì sān zhĕ shì bù bèi shēn ài de nèi gè]
'The Third Party Is Never Truly Loved' alludes to the painful reality of being involved in a love triangle as the outsider—the person who doesn't receive true, deep affection. It's about feeling secondary in one’s affections or never reaching the desired depth of a relationship.
