If only good existed in it, then there would be no human beings there. Humans are fallible and capable of both good and bad. Nobody is perfect so we can't expect anybody to be all-good.
In reality, if one of them.was grossly obese, were missing all their teeth or were just simply not attractive to the other, then they wouldn't have met a 2nd time.
It is possible to be attracted by words and online personality. But the physical attraction also has to be there. That is why meeting in real life is a necessity.
