On the wedding day, the MC asked "Will you marry him" and replied "I don't want to". What are the consequences?

If that's the case, there will be a scene where the bride runs away. ...

I don't like not waiting until I go to the auditorium to realize that separation may not make me a friend, but refuting his face in public has turned the biggest happy event of my life into the biggest joke. I'm afraid no one has such a big mind. . .

If you don't want to, you might as well postpone the wedding and give each other time to adapt. It is really impossible to say no in private.
