致命迷人笑
[zhì mìng mí rén xiào]
The name literally says 'Deadly Charming Smile,' indicating that this person’s smile holds a level of charisma and attractiveness that can metaphorically cause others to lose their composure or be drawn into an overwhelming attraction – it’s so captivating that it feels nearly overwhelming or dangerous, much like when one describes love as fatal or intoxicating.
