毕竟久伴不及深爱
[bì jìng jiŭ bàn bù jí shēn ài]
Ultimately, long companionship can never compare with deep love ('毕竟久伴不及深爱') conveys that although it is valuable and meaningful to have long-term relationships with others, this does not mean love. The depth and intensity of true love can surpass just spending time together. It implies people who accompany us may leave at any time. The feeling described by this idiom reflects nostalgia about an unfulfilled romance.
