Tight refranation between Mercury and Venus - Spot the Mistake!

Mercury and Venus have been following one another at even pace for a good week now, and the first assumption is that the conjunction will be perfected. Mercury, the swifter planet, is applying to Venus. However, Mercury falls 3' short of the conjunction before he runs out of breath and start to slow down before entering retrograde motion. It's a refranation. In terms of clients I was approached by a couple who were sincerely devoted to one another and likely to be companions for many years, according to this configuration, however not marry, as may be the case. I wanted to inspect a chart that may show the configuration in general.

Can anyone spot the mistake?

The dragon swallowed venus.
