This is looking like a battle of the acting greats with Lee Sung Min and Song Joong Ki going mano-a-mano in the new teaser for Reborn Rich (The Youngest Son of the Chaebol). jTBC has slipped a bit since that year stretch where it was putting out unexpected strong dramas but remains capable of producing quality fare. Reborn Rich takes Song Joong Ki from household help to the rich grandson of the family in a fantastical (karmic?) twist of fate and all he wants is vengeance as to be expected. I love the tension in this teaser, so much conveyed in the eyes and body language.
