Watch: Hyeri's Seemingly Kind Gestures Make Chung Su Bin Uneasy In New "Friendly Rivalry" Preview

Feb 08, 2025

Upcoming drama “Friendly Rivalry” has unveiled a gripping new preview ahead of its premiere!

Based on a popular webtoon, “Friendly Rivalry” is a mystery thriller set at Chaehwa Girls’ High School, an elite institution for the top 1 percent in South Korea, where cutthroat academic competition takes place between the students. Chung Su Bin stars as Woo Seul Gi, a transfer student who becomes entangled in her classmates’ hidden ambitions—and the secret behind the mysterious death of her father, a former college entrance exam question setter.

In the newly released video, Yoo Jae Yi (Hyeri) presents a neatly ironed school uniform to Woo Seul Gi, replacing her worn-out one. Confused by the unexpected kindness, Seul Gi questions Jae Yi about her motives.

Rather than answering right away, Jae Yi insists that Seul Gi change and assists her with unbuttoning her shirt. As Jae YI helps, she discovers a burn scar on Seul Gi’s collarbone, which makes Seul Gi quickly cover it up.

When Seul Gi tries on the new uniform, she grows more suspicious. Jae Yi seems to know far too much about her personal history—her size, her academic record, and the fact that she’s never had private tutoring. Jae Yi says all she wants in return is detailed information about how Seul Gi studies using the materials she provides.

As the preview nears its end, the tension escalates further when Choi Kyung (Oh Woo Ri) and Joo Ye Ri (Kang Hye Won) enter, and Jae Yi pulls Seul Gi into a closet to hide. While the other two classmates gossip about Seul Gi, Jae Yi doesn’t seem to care and places Seul Gi’s hand on her own chest, hinting at a deeper obsession and leaving viewers wondering just how far she will go for her mysterious motivations.
