七秒忘七年痒三秒梦三年痛
[qī miăo wàng qī nián yăng sān miăo mèng sān nián tòng]
In Chinese culture, there's a saying that fish have a 7-second memory. This nickname suggests a mix of forgetting (7 seconds), the longing and itchiness in a relationship over seven years (seven-year itch), short-lived dreams (three seconds), and deep pain spanning three years, blending various time frames with emotional states.
