Romantic comedy about boys and girls in school

I can't remember the name of a film, every chance its not very good but its annoying me.
I can only remember one scene and a little background.
Its about 2 girls, 2 boys, they are all in school together, 1 of the girls is overweight and 1 of the boys bullies her quite a lot, fast forward years later, the (now) ladies bump into the (now) men who are opening up a restaurant. 1 of the men is interested in 1 of the ladies, neither remember who the ladies are and that they bullied them.

what year is the movie?

I've changed the thread title to be more descriptive, per the warning beneath the title field:

Is it similar to Muriel's Wedding?
