Cuties Jackson and Youngji are at it again!  The December 9 edition of 'Roommate' showed more bickering between the two, causing the other cast members to tease them and jokingly say they will end up getting married.

When the two had to get into the car driven by Jo Se Ho with actor Lee Dong Wook in the passenger seat, Youngji complained at having to scoot over so Jackson could slide in next to her, asking why he had to come in on her side.  Afterwards, he offers a peace handshake, saying they should not fight.

Jo Se Ho says, "If you guys keep fighting like that, you'll end up marrying," to which Lee Dong Wook added, "That's right.  If you keep fighting, we're going to make you marry," causing the two in the backseat to laugh.
