'Pyramid Game' Episode 7: Class 5 Goes To the Beach

In "Pyramid Game" Episode 7, Class 5 goes out on a field trip. However, tension still fills the air after Sung Su Ji (WJSN Bona) learns about Baek Ha Rin's (Jang Da Ah) threat.

At the beach, Sung Su Ji receives texts from her classmates about her plans in destroying the game. However, she contemplates whether to transfer or not for the sake of her father.

Sadly, Baek Ha Rin also manipulates her friends. The mastermind then uses Shim Eun Jung (Lee Joo Yeon) and Song Jae Hyung (Oh Se Eun) to strip her off her friends.

Bang Woo Yi (Ha Yul Ri), who's feeling betrayed, pushes Baek Ha Rin into the pool despite knowing full well that the other couldn't swim. Thankfully, Shim Eun Jung saves her.

Im Ye Rim Gets Upset

Baek Ha Rin lies about being pushed into the water to keep the teachers off their business. The other girls notice how she seems to have lost her mind.

Later on, Baek Ha Rin, Seo Do Ah (Shin Seul Ki), Kim Da Yeon (Hwang Hyun Jung), Go Eun Byul (Jung Ha Dam) and Shim Eun Jung all share rooms for the night, leaving Im Ye Rim upset.

Sung Su Ji shares rooms with Myung Ja Eun (Ryu Da In), Song Jae Hyung, Im Ye Rim and Cho Yu Rim (Kim Min Ji) who is then called out for backstabbing Myung Ja Eun in the past.

The newcomer defends herself, saying that she was a victim as well. Later that night, the girls bring a cake to celebrate Sung Su Ji's birthday, making others notice how close they are.

What Happened In the Past?

Cho Woo Ri (Joo Bo Young) stalks Im Ye Rim's Instagram and sees her three new friends, making her feel left out. She also recalls how Baek Ha Rin bullied her, causing her to panic.

Later, Im Ye Rim and Song Jae Hyung receive threats from Baek Ha Rin while the other girls thank Sung Su Ji for giving them courage at the recent dodgeball game.

It's revealed that the girls told Sung Su Ji about Baek Ha Rin blackmailing them to turn them on one another. The episode ends with Sung Su Ji refusing to delete the recordings on her phone.
