不及一人不及久伴
[bù jí yī rén bù jí jiŭ bàn]
'Not as Good as Just One Person and Unfit for Long Companionship' indicates modesty about finding a perfect match or expressing incapability to maintain a long-lasting companionship due to personal inadequacies or low self-esteem, suggesting loneliness while yearning for close bonds but unable to sustain them, maybe because they're always thinking no one is good enough as their ideal partner or feeling unqualified to stay alongside others for very long
