Be healthy always, be respectful and have a happy expression even in case you're disappointed with the amount you'll receive this New Year. Oppa is bringing you your sister-in-law to greet my parents, well.. Anna, on the screen, she and... sorry for this bad prank. I should give an award to whoever photoshopped this. However, I don't like (me)-- Apparently I'm the only one who likes it, and it hurts my pride.. shivering..
