你的眼里有光那是因为有你
[nĭ de yăn lĭ yŏu guāng nèi shì yīn wéi yŏu nĭ]
'Your eyes shine only because of you'. This could mean either admiring someone else for bringing light into the user's life or suggesting they are their own best light and strength. There are nuances depending on interpretation, either self-love or romantic infatuation.
