我就是你命里的劫中劫你就是我心里的结中结
[wŏ jiù shì nĭ mìng lĭ de jié zhōng jié nĭ jiù shì wŏ xīn lĭ de jié zhōng jié]
A rather dramatic declaration: 'I am your fate's calamity within calamities; you are my heart's knots within knots.' It expresses feelings of being a challenge to one another in terms of relationships or fates, signifying intertwined destinies full of trials and emotional intricacies.
