相諾与沫却厌倦到终老相忘江湖却怀念到哭泣
[xiāng nuò yŭ mò què yàn juàn dào zhōng lăo xiāng wàng jiāng hú què huái niàn dào kū qì]
Promises made with泡沫(foam) become tiring over time until forgotten, yet longing remains so strong it causes tears. Here, foam represents transient and fragile promises. There's a contradiction: the promises fade with time leading to forgetting, contrasting against the intense yearning.
