你的城堡我的牢为你我画地为牢
[nĭ de chéng băo wŏ de láo wéi nĭ wŏ huà dì wéi láo]
Your Castle Is My Prison; We Draw Circles To Be Imprisoned. This describes being deeply bound by feelings, usually in a negative way as a prisoner would be confined within a cell. Here 'your castle' might represent safety, desire, love etc., which also means the person is trapped in the relationship.
