对你掏心掏肺对你没心没肺
[duì nĭ tāo xīn tāo fèi duì nĭ méi xīn méi fèi]
'Being Entirely Sincere for You, Yet Also Utterly Indifferent at Times.' This name reflects complicated emotions toward a certain person - sometimes sincere to the point of laying bare one's heart and entrails, while other times completely cold and indifferent as if not caring at all.
