This story has a little unconventional format and I thought it might be helpful to explain it to you.

It is divided into 7 sections with 2 parts each. Each section will be focused on a different couple, but everything is taking place in the same ball. 

The host is unknown to all except himself/herself. Among the fourteen people this story follows, one is secretly the host who organized the whole event.

Can you figure out who it is?
