Though the two are already a virtual couple, 2AM's Jinwoon made it official by proposing to his onscreen wife Go Jun Hee on the latest 'We Got Married 4'!

Viewers may remember from last week that the two went on a trip to Japan. It was there that Jinwoon put on a surprise event for the actress, having her come across an engagement ring. 

He asked her, "Jun Hee, will you marry me?" Go Jun Hee, who is six years older than the idol, responded with a surprised expression, "I'm your noona," and accepted.

This wasn't the end of Jinwoon's special event, however. He had also prepared a wedding, and the two walked down the aisle arm in arm in white.
