忘了七秒碎了心
[wàng le qī miăo suì le xīn]
Literally translates to 'Heartbroken for seven seconds and forgotten,' which could refer to an attempt at moving on or letting go after a brief moment of pain. Fish have a memory span of about seven seconds according to popular belief; hence, this nickname might suggest the fragility and ephemeral quality of feelings, trying to imitate the brief memory span by forgetting past hurt within a similar time frame. Or it could imply someone pretending that memories disappear as fast as fish do but actually carrying wounds deeply inside oneself.
