Ask anyone who loves K-drama to name a breakout star of 2021 and the name on most people’s lips is Jung Ho-yeon.

When the casting for Vincenzo was first announced, many raised eyebrows as to who will star opposite Song Joong-ki in his comeback drama. The name Jeon Yeo-bin didn’t ring a bell for many. But now she’s a rising rookie actress on everyone’s radar, oftentimes called a rookie monster due to her versatile acting skills even as a newcomer.

Jeon’s portrayal as the feisty Hong Cha-young might have made her a superstar but the actress has already wowed critics in After My Death—her first-ever lead acting project—which earned her several acting nominations and awards.

In Be Melodramatic, her first K-drama lead role, she bagged a Best New Actress nomination at the Baeksang Arts Awards. This year, Jeon’s movie Night in Paradise was also released on Netflix which catapulted her popularity even further.

It might not be fitting to call Koo Kyo-hwan a breakout star considering that the actor has been raking in acting awards as early as 2018.
