他会发光你会吸光我会灭光
[tā huì fā guāng nĭ huì xī guāng wŏ huì miè guāng]
This implies 'he radiates brightness, you draw that light, while I fade out.' It's poetic about the relationship dynamics where certain individuals stand out, others get influenced positively, leaving another behind as if extinguished, expressing admiration, competition, and self-effacement.
