Kristina is worried because her parents have not arrived. Could it be that her dad got upset with her and decided not to come? Oh, no Kristina, Aaron adores you, and of course he's coming to the wedding! 

(What actually happened is that the Wassem's farm is too far away from the wedding venue, so they were late, and on top of that they got stuck at the entrance, so they weren't on time to sit down, Kristina and Liang couldn't start the ceremony and they got the "missed the wedding" moodlet. You know, game stuff, but the wedding took place anyway😉).

Kristina had to ask Liang to get married once more via the arch, and it all started again.
