School is in session again at McKinley High! "Glee" is set to return on Thursday night (September 13) for season four, and it promises a whole lot of shakeups. With the show's central characters graduating and some moving to different states, the name "New Direction" is taking on a whole new meaning.

When MTV News recently caught up with "Glee" star Harry Shum Jr., he filled us in a little on what to expect this season and what's next for his character, Mike Chang.

"There's going to be a show within a show," Shum told us. "They're following different parts, not just high school anymore. This season not only finds us in Lima, Ohio, but in New York City, with Rachel struggling at New York Academy of Dramatic Arts and dealing with her heartbreaking breakup with fiancé Finn.

Finn (Cory Monteith) and Rachel (Lea Michele) aren't the only couple dealing with issues though. Darren Criss even told MTV News he's hoping for some "drama" between his character, Blaine, and Kurt, played by Chris Colfer. Meanwhile, Shum's character, Mike, has accepted a scholarship to ballet school in Chicago, which takes him away from his girlfriend, Tina (Jenna Ushkowitz).

"There [are] so many places they can take the character," Shum added. "He ended up in Joffrey Ballet in Chicago, so we'll see if he ended up there or if he's going to come back.

"I'm hoping for reality: At any point at any time, something could blow up and someone could break up ... to me that makes good television as well. Because there's going to be fights with couples, they're always going to fight, break up, come back together, break up and you're just like, 'Oh my god, what are you doing?' But that makes great television."

But even though he wants to see great television, of all the couples, Harry hopes Rachel and Finn find a way to work it out. "The 'Finchels' and all that, I think all of them are all great together," he said. "I wouldn't want anything bad for any of them or for them to break up so, man, I'm rooting for all of them. I'm a sucker for love."

Of course, with "Glee" it's not all about relationships, but about the singing as well. This season boasts a new crop of guest stars like Kate Hudson and Sarah Jessica Parker, and more tribute episodes, including the one and only Britney Spears.

"You can never get enough of Britney," Shum said. "She has so many hits you could do probably, like, four or five different episodes of Britney."
