你没和我说过我爱你最深情的告白是陪伴
[nĭ méi hé wŏ shuō guò wŏ ài nĭ zuì shēn qíng de gào bái shì péi bàn]
It implies a deeper expression of love through action, not words: “you’ve never said 'I love you' but the most profound declaration of love is companionship”. The best love doesn't need loud words, just steadfast support and companionship.
