时光叫我不敢轻易说爱
[shí guāng jiào wŏ bù găn qīng yì shuō ài]
This translates to 'Time makes me not dare to say love lightly.' It conveys the feeling of hesitation in expressing one’s love, possibly due to the fear of time or life changing things too quickly. This could be from past experience or a general cautiousness towards commitment.
