On July 24, the first episode of "Reply 1997" aired and the character Siwon (Eunji), bullied Yunjae (Seo In Guk) to record episodes of a drama she can't watch as she goes to Daegu to watch a HOT concert. She is also seen kicking him when he says something that she doesn't approve of. The two rookie actors shared a kiss in a scene of the drama as well.
This drama features a story that reflects back to the 90's, showing popular groups like HOT and Sechs Kies.
Seo In Guk, A Pink Eunji, Eun Ji Won, INFINITE Hoya, Lee Shi Yeon and Shin So Yul star as the main cast in 'Reply 1997.'
