颗心只为你魂牵梦绕个人只为你画地为牢
[kē xīn zhĭ wéi nĭ hún qiān mèng răo gè rén zhĭ wéi nĭ huà dì wéi láo]
Indicates an intense love and attachment to one particular person. Heart fully belongs and is completely obsessed with this person, unable to free itself from the attachment, akin to being confined willingly in a cage because of one's love.
