是你是我理不清的相欠
[shì nĭ shì wŏ lĭ bù qīng de xiāng qiàn]
'It’s you, it’s me—the unresolvable debts.' This likely refers to unresolved issues or complicated relationships between two people where each owes something, metaphorically speaking, to one another. It implies a difficult entanglement or an unresolved situation that neither side can clarify or settle.
