MB is for a Master's in Business degree. Supposedly. It's also for:

Multiple Bed-hopping: Definitely Kimmy's favorite subject. And who cares if her conquests are already taken? If only business school offered a minor in boyfriend embezzlement...

Monogamous Boyfriend: Russ didn't intend to be unfaithful--he never thought he'd find one woman who wanted him, let alone two. But since he can't even pick a major, how can he choose a girlfriend?

Marriage Bait: Layla's obsessed with perfection: perfect grades, perfect six-figure salary, perfect New York investment-banker husband. But you know what they say about the best-laid plans...

Misleading Behavior: Jamie might be a jokester, but he has more secrets than the CIA. Including one whammy that could get him expelled.

Temptations. Drama. Beer bashes. How will they ever find time to study?
