毕竟是我深情不及她久伴
[bì jìng shì wŏ shēn qíng bù jí tā jiŭ bàn]
This phrase conveys resignation and sorrow in comparison to someone else. The speaker admits that his profound love doesn’t endure as long as her presence has done, signifying perhaps regret for missing out on someone due to not showing enough perseverance in the early stages of the relationship.
