Amber and Henry might think they're like siblings, but they almost seem like an old married couple, especially as Amber also said on their joint 'Happy Together 3' appearance this week that she nags at him a lot.

The MCs asked the responsible Amber, "Do you write out your financial records?" as in does she keep a book on her spendings and such.  She replied, "As I'm an adult, I even meet up with a tax accountant.  Because I need to do the American [tax] too," and her financial records were revealed on the show.

Then she said in relation to Henry, "I worry about oppa; he's profligate with money.  I maintain my [finances], but he doesn't.  It's really frustrating.  But it's already been five years since I've told him.  The only thing that comes out of me is nagging.  When we came from overseas together."
