他虽不是高富帅但很爱我她虽不是白富美但我爱她
[tā suī bù shì gāo fù shuài dàn hĕn ài wŏ tā suī bù shì bái fù mĕi dàn wŏ ài tā]
It expresses acceptance of mutual love despite both partners not having ideal appearances. Literally translates to 'He's not tall, rich, and handsome but he loves me; she's not fair-skinned, wealthy, and beautiful but I love her'.
