他不是太阳却把我照亮
[tā bù shì tài yáng què bă wŏ zhào liàng]
Suggests admiration for someone: 'He is not the sun, but he lights me up'. The user probably feels enlightened or significantly impacted by another person who brings positivity into their life despite not having all attributes of an ideal person ('the sun' can represent the epitome of brilliance).
