'Kokoro' means 'heart' ( the feeling/emotion not the body part ) in japanese, so when someone says ' my kokoro is brokoro' it means their heart is broken, or they are feeling down or heart broken.

"Kokoro" is Japanese for heart, while "doki doki" is an onomatopeia for heartbeat. This phrase is often used ironically or in a humorous context to express admiration or love.
