你的光很亮却不温暖
[nĭ de guāng hĕn liàng què bù wēn nuăn]
The phrase means 'Your light blazes bright but gives no warmth', expressing that although the other party has a great outer appeal (charisma or popularity, etc.), it does not mean emotional intimacy; instead, it could suggest the presence feels remote or unapproachable.
