When cheating is justified

Things at University seem to be doing okay. The students are studying hard and getting good grades, but other than that, nothing interesting has happened.
...or has it?

It looks as though Bex has made herself a new friend. In fact, she has 5 lovers, and NONE OF THEM KNOW ABOUT EACH OTHER.
Well, except for Terrance and Angelo. But that's a different story.
Speaking of Angelo, one night at dinner, no one knows how, but Angelo and Sheila fell in love. All he did was throw a bit of food at her - hardly romantic!
Anyway, now Angelo wants to PROPOSE to Sheila. Never mind that he's already engaged to Bex. Oh, and just forget the fact that Sheila is dating his brother.
How will this turn out?
