One Wife, Multiple Weddings

"On the day of my wedding with my girlfriend, I was unexpectedly informed by the hotel that our ceremony had to be postponed by a couple of hours.With no time to notify relatives and friends of the change, I had to rush to the hotel entrance to intercept guests.Upon arriving, I was stopped at the door by security, who told me that a wedding was currently taking place inside.The host's voice could be heard as I saw my girlfriend, wearing a veil, smiling and extending her hand to a man who was half-kneeling.In the audience, all the bride's relatives who were supposed to attend our wedding were seated, clapping and cheering.The man on stage was her dream guy and also my current superior.Seeing me causing a commotion, my girlfriend warned me, "I'm just helping out. Alex is your superior. I'm also doing this to help you. Don't cause any trouble."Just helping out? I had booked the wedding venue, chosen the time, designed the wedding dress, and personally sent out the invitations.How could a wedding be rearranged so suddenly?I looked coldly at the ring box the man was holding."It seems my taste is quite similar to my yours. If that's the case, this diamond ring is yours, including the wife."My girlfriend finally panicked."
