钻石你的光光芒我的心
[zuàn shí nĭ de guāng guāng máng wŏ de xīn]
This poetic name loosely means 'diamond shines your light, brilliance into my heart'. It romanticizes admiration where someone’s sparkle (charm/personality) has touched another’s feelings deeply, akin to love struck or awe-struck by admiration.
