七生七秒

Translated directly as 'seven lives seven seconds'. In Eastern cultures influenced by Buddhism, people believe humans reincarnate for several lives (like 'qisheng' means seven incarnations). The second part could imply something happening within an instant or emphasize brevity against the vast span of time spanning lifetimes. It also conveys deep emotion, suggesting that even a single moment or event in life is precious enough to impact multiple lives.
