I'm Still Embarrassed

After watching the movie, I sent the two babies home and wanted to go to the supermarket to buy some ingredients. I planned to cook a feast for them tonight.

An hour later, when I returned from the supermarket with a bag of groceries and arrived at the apartment building, there was a sudden commotion in front. There were many people clustered together, it was bustling and I didn't know what they were doing.

I've never been interested in such things. Just as I'm about to walk around the crowd and enter the apartment, I noticed something wrong.

Wait a minute, the man standing on the platform in the middle of the crowd. Who else could it be but my disgusting fiancé, Peter?

This guy came down to my apartment building and brought so many people with him. What is he trying to do?
