Upcoming K-drama Bitch X Rich, starring Red Velvet‘s Yeri, has released its first teaser. Watch it below.

Bitch X Rich is set to follow Kim Hye-in (All of Us Are Dead‘s Lee Eun Saem), a student from a poor family who gets a chance to study at the prestigious Cheongdam International High School in exchange for her silence after she witnesses a murder.

However, once at Cheongdam International High School, Hye-in comes face to face with Baek Je-na (Yeri), the heir to a chaebol and the most popular girl in school.

The new teaser for Bitch X Rich opens with Hye-in opening her new school locker for the first time, only to find a sign reading “Welcome to Hell” with a mysterious pair of heels. Je-na then tells her: “As long as you’ve been caught by Baek Je-na, your school life will be ruined.”

“What, are you a transfer student? Who do you think I am? If possible, try staying out of my sight at school. You beggar,” Je-na adds later in the clip. “If this is an aristocratic school, I’m royalty.”

The teaser also features scenes of Hye-in and Je-na fighting with one another, as well as a dramatic seen of Je-na pouring red wine over Hye-in’s white dress during the school prom.
