From an objective standpoint, they’re both the same, and if both couples died without repenting, they’d be damned just the same. It would appear, though, that perhaps the first couple was trying to wait, but gave in to temptation (in which case, it being just 10 days b/f their marriage, they would probably feel awful about it. I’m just speculating, though). The 2nd couple would appear to not care at all about fornication being sinful, in which case they would seem less likely to repent. Being only on the 2nd date, they would also have a LOT more time to continually fall into sin than the first couple, so they’d be “worse off” in that regard.
