Explanation: Following a week of dating, they went shooting each time and failed to hit the target. However, after six months of dating, their skills increased and they were able to aim more precisely since they had been in love for a long time.
More details: They went shooting every time they spent time together after a week of dating, however they failed to hit every shot. This may be interpreted as a metaphor for their early relationship phases, when they are still figuring things out, unsure, and not quite in sync. But after six months of dating, their relationship had become closer and more solid.
Like honing a skill, their love and communication had become stronger over time, which made them more accurate and self-assured in their relationship and in shooting. This demonstrates how relationships take time, patience, and effort to develop and get better, just like any other ability.
