Love you for 70 seconds in French.

You seem to have made a mistake. I love you for 80 seconds. This is already a fixed statement. I guess I heard the expressions of Liu Ye's son and a pair of dads on TV, but I got it wrong.

A French love story:

There is only one second in a minute, but I like one more second.

1 minute is only 60 seconds, but I love you for 20 seconds more.

There are 60 seconds in a minute, and I love my father for 80 seconds.

I think so, the extended meaning of this sentence: there are 60 seconds in a minute, which is an eternal truth, but the time limit of my love for you has exceeded eternity.

I hope my answer is helpful to you. If you are satisfied, please adopt it. If you don't understand anything, please ask O (∩ _ ∩) O. Thank you.
