暖阳少女却刺心薄情少年欲暖心
[nuăn yáng shăo nǚ què cì xīn bó qíng shăo nián yù nuăn xīn]
'Warm sun maiden who stabs the heart; cold-hearted youth desires a warm heart.' This portrays two characters: one who seems friendly and warm on the surface but hurts others, and another who comes across as indifferent yet yearns for connection and warmth.
