当我像你爱我一样爱你时
[dāng wŏ xiàng nĭ ài wŏ yī yàng ài nĭ shí]
This means 'when I love you just as much as you love me'. It speaks of reciprocated love, reflecting a balance in affection and dedication between two people. It could imply either mutual appreciation already present or an aspiration for equality in love.
