放你走微笑灿烂的像只狗
[fàng nĭ zŏu wēi xiào càn làn de xiàng zhĭ gŏu]
Letting you go with a smile as brilliant as a dog's. Conveys a feeling of releasing someone while still smiling, possibly indicating happiness for the released person despite the personal pain; uses a dog's smile as a metaphor for genuineness and brightness.
