心如柠檬酸甜子可知
[xīn rú níng méng suān tián zi kĕ zhī]
Loosely translated as 'My Heart Resembles Lemon Sweet Sour Only You Can Understand', it compares feelings experienced within someone to flavors. A mixture of sourness and sweetness indicates bittersweet experiences; those moments filled with joy accompanied by melancholy too. Such an ID expresses sentiments needing empathy from another soul-mate alone.
