I am in a similar situation. I didn't invite the wedding. On the day of the reception, I invited several close friends to buy balloons, flowers and ribbons to decorate the banquet hall. Projectors and audio hotels are provided free of charge, and a friend with good eloquence is invited to act as emcee temporarily. The projector plays a piece of your love story or a touching piece ... The scene is not very big, but it is very warm.
