我本将心向明月奈何明月照沟渠
[wŏ bĕn jiāng xīn xiàng míng yuè nài hé míng yuè zhào gōu qú]
Originates from classical Chinese literature, symbolizing high aspirations and hopes for sincere friendship/love only met with indifference. It implies that efforts towards others were once noble, aiming as lofty as the moon, yet those same intentions ended up being disregarded, much like shining into ditches. In short, it conveys a sentiment of unrequited affection and misunderstanding.
