Premise and characters

The series is set at Joongang High School, where 18-year-old students are measured against "perfect" standards and pushed into fierce academic competition, chasing grades rather than dreams. As they fear disappointing their parents, they begin approaching taboos: risky relationships, secret sexual activity, and sneaking in drinking and smoking during their last adolescent years before adulthood.²

Main characters. Park Ji-yu (Kim So Hui) is a quiet high schooler with average grades who relies on her best friend Chan-sung and, at the start, has no other friends. No Chan-seong (Kim Eo Jin) is her boyfriend, passionate but complex inside. Kang San (Gong Ju Han) appears perfect but suffers from loneliness. Seo Ara (Kwon Hui Song) is a new student whose friendship draws Ji-yu into a girl group. The supporting circle includes Jeong Mi-na (Moon Ji Won), who conceals her anxiety, and Kim Ye-ri (Kim Ye-rim), described as cynical but smart.⁵^•²^•⁸

The episode arc follows Ji-yu's shifting relationships: a startling incident with the senior student Do-ha shakes her world in episode 2, her bond with Chan-sung falters as she spends time with new friends, rumors put her at the center of a conflict with Mi-na in episode 5, and her attempt to fix a mistake makes the situation worse in episode 6.⁸

Production and release

STUDIO X+U announced the series on September 9, 2024, positioning it as a follow-up to its earlier high-teen dramas High Cookie and Night Has Come and as the start of a diversification into new genres. The production used an all-rookie cast to achieve what the studio called a hyperrealistic directing style.¹^•⁶

Cross-media release. To make the teenage story feel more realistic, the studio adopted a "3Way cross media" strategy: the drama itself ran on U+ Mobile TV at midnight each Monday, while behind-the-scenes videos of events in the story were uploaded to YouTube before episodes aired, and Instagram was used alongside them to build immersion.⁶^•¹ LG U+'s chief content officer Lee Deok-jae framed the show as the foundation for an original high-teen universe built on new actors and realistic stories aimed at the MZ generation.¹

Beyond U+ Mobile TV, the series became available on KOCOWA+ for international viewers from around its premiere², and it later streamed on OnDemandKorea, where episodes are listed from September 8 to October 27, 2024 with a 14+ rating³, and on Apple TV in some regions⁸.

Reception

The poster featuring an all-rookie cast made the series highly anticipated before release, according to KOCOWA's coverage.² Review scores have been moderate: the aggregator Dramoly lists 7.3 out of 10 based on MyDramaList ratings⁷, and the Korean service Kinolights shows a 66.7 percent rating from a small number of user reviews.⁵

Critical views. The BL-focused review site BL Watcher scored the series 7.4 out of 10 and described it as an unofficial Korean remake of the Norwegian teen franchise SKAM, with similar plots and characters to that show's first season but a more reserved, tamer treatment of its gritty themes. It noted that the BL subplot, involving a closeted gay character and a short kissing scene, is minor and only emerges near the end, while the straight couple's relationship is the main focus; the review praised the friendships and the mildly happy ending centered on Ji-yu's growth.⁹ A review in Abstract AF! highlighted the teen girl group's everyday scenes, such as bowling, board games, and pajama parties, as the most enjoyable parts, and described the background score as understated in a way that complements the story.¹⁰ An Indonesian review in IDN Times judged the plot conventional but accessible across generations, and noted that the short episode length made the series easy to fit in.¹¹
