沉浸在沵阳光的笑容中那抹笑容如同毁灭的光
[chén jìn zài mĭ yáng guāng de xiào róng zhōng nèi mŏ xiào róng rú tóng huĭ miè de guāng]
This refers to being completely captivated by someone's radiant smile, comparing its impact to the destructive power of light. While paradoxical, it means the charm of the smile feels almost overpowering but not necessarily negative—it's overwhelming due to its beauty.
