我们的友谊像糖甜到忧伤
[wŏ men de yŏu yì xiàng táng tián dào yōu shāng]
This nickname reads 'Our friendship is like candy-sweet until it hurts.' This symbolises intense sweetness of purest of bonds shared by two or more people but it may also indicate pain or loss of the beautiful bond that happened at some point in past.
