薄情薄唇
[bó qíng bó chún]
The name 'Heartless with Thin Lips' might convey two images. On one hand, it can symbolize an individual who looks cold with naturally thin lips. Alternatively, it indicates someone unfeeling and callous (having 'thin affection'). The second meaning may be closer as '薄情'(thin feelings/love) often refers to a lack of sentiment in Chinese cultural context.
