My Husband Changed At The Wedding Venue

Three days before the wedding, my fiancé cheated on me with another woman.
To make matters worse, he had the mistress stand as a wedding singer.
Watching my fiancé sing with his mistress gazing at him wistfully, I finally realized.
I can’t go through with this marriage.
I declared clearly to the bewildered officiant and guests who were staring at me blankly.
“I can’t do this, this marriage.”
Just as I was about to leave, amid the chilly atmosphere that had settled in, he suddenly stood up in the midst of the already chaotic wedding hall.
“Then marry me.”
“Are you crazy? What kind of madness is this at someone else’s wedding?”
“Someone else’s wedding just ended, now it’s my wedding.”
But to receive a proposal right after my wedding fell apart.
No, why are you like this? When did we become a couple?
