你是阳光我怕刺眼
[nĭ shì yáng guāng wŏ pà cì yăn]
This internet nickname 'You Are Sunshine, I'm Afraid of Glare' implies that the other person is warm and bright in the user's life, much like sunlight. But it's so dazzling or overwhelming that the user almost cannot face it directly, conveying the idea that someone has too much of a positive impact which can sometimes be hard to deal with.
