你爱的人一定长得很漂亮吧开玩笑吧你未免太自恋了吧
[nĭ ài de rén yī dìng zhăng dé hĕn piāo liàng ba kāi wán xiào ba nĭ wèi miăn tài zì liàn le ba]
Sarcastically saying 'the person you love must be very beautiful huh? Come on, you must be too conceited,' this reflects doubt towards someone's assertion that they love based purely on appearance, hinting at possible arrogance or self-centeredness.
