女生缘不好却爱她的少年男生缘很差却爱他的少女
[nǚ shēng yuán bù hăo què ài tā de shăo nián nán shēng yuán hĕn chā què ài tā de shăo nǚ]
This expresses a scenario where despite facing difficulties forming relationships ('bad luck in love') or being appreciated by the opposite gender, a boy continues loving a girl who isn't widely popular and vice versa, signifying pure affection untouched by external validation.
