无你世界无我无心
[wú nĭ shì jiè wú wŏ wú xīn]
'Without You World There Is Neither Me Nor Heart', which poignantly conveys that without another particular person's existence within one's world, there wouldn't be any significance or reason for oneself or their emotional essence to endure. It highlights the immense influence a significant other plays in one's identity and well-being.
