# Not the Same Person You Used to Know

Not the Same Person You Used to Know (Korean: 니가 알던 내가 아냐) is a South Korean variety show which premiered on Mnet on December 20, 2018. It was aired every Thursday at 23:00 (KST).
On May 8, 2019 it was confirmed that the show will return for a second season, with DinDin the only cast member from Season 1 to return. The new members include Lee Sang-min, Boom, Jang Sung-kyu and Jung Hye-sung. The second season, named V2, was expected to air every Thursday at 20:00 (KST) starting from June 27, 2019. The season ended on August 15, 2019.

## Format

Acquaintances of a celebrity (friends, managers, parents, siblings, etc.) are invited to answer a quiz about the celebrity to see if they know him/her as well as they think they do. For instance, they will have to watch videos of the celebrity and predict his/her next actions.
For Season 2, a slightly different change is that 4 guests related to the celebrity are invited to the show and take on the Non-related Observers (the cast members except Jang Sung-kyu) in a quiz about the celebrity. A total of ₩3,000,000 is up for grabs and the team with more winning money wins the quiz.
