许我七日暖给你三寸光
[xŭ wŏ qī rì nuăn jĭ nĭ sān cùn guāng]
'Allow me seven days of warmth, offer you three inches of light,' implies exchanging a temporary comfort period with genuine care or effort on both sides within constraints. It can also imply a promise of making moments count deeply even in small amounts of time spent together.
