愿做你的蝴蝶少女愿做你的狼族少年
[yuàn zuò nĭ de hú dié shăo nǚ yuàn zuò nĭ de láng zú shăo nián]
This expresses two contrasting desires: one is to be like a delicate butterfly girl (feminine and romantic), the other like a fierce wolf boy (masculine and wild). It signifies wanting to transform oneself into whatever role the beloved might desire.
