Meeting my ex-lover again after many years apart

Met my ex-girlfriend after many years and ended up having a lot of sex. We met through the introduction of a friend. They started dating right away, and it was supposed to be a countdown until they started dating, but a sudden long-term business trip abroad turned it into a blank slate. The two, who cannot let go of their feelings, will meet again within a short period of 24 hours. The two of them conveyed their emotions to each other. In a situation where they did not know when they would meet again, as long as time allowed, they never regretted a moment of not forgetting each other's closeness and expressions, earnestness and passion.
