It is a dramatization of the webtoon of the same name written by Song Chae-yoon, illustrated by Shim Jae-young and produced by Ylab, and, compared to the original work, it added the mystery surrounding Woo Do-hyuk's death. Friendly Rivalry was directed by Kim Tae-hee, who co-wrote the script together with Min Ye-ji. At the series' press conference, Kim stated that she accepted the offer to direct it immediately when she was first asked to write the script in 2021 because, \"First, there was no good person among the characters, and second, the fact that there were a lot of women was appealing.\" She also thought that it would be fun to picture \"these slightly crazy girls, each hiding their own secrets, engaging in a bloody competition and alternatively becoming friends or enemies.\" As for the script, Kim said that she wanted the drama to be persuasive to the viewers and hoped that the characters would be ultimately understandable, stating \"Our work is a story about everyone who has not learned how to lose in a society that only teaches how to win. If you know that there's definitely a next chapter in life even if you fall and fail, you just have to dust yourself off and get back up and start your own race again. I wrote and directed with the hope that Jae-yi, Seul-gi, Ye-ri, and Kyung will know that the true competition in life begins from that moment.\" During the four years of development, the director met with female high school students, and consulted with psychiatrists and teachers. ===Casting=== On July 23, 2024, Studio X+U announced that Lee Hye-ri, Chung Su-bin, Kang Hye-won, and Oh Woo-ri would work together to tell the story of high school girls. On July 24, Andbut Company stated that Choi Young-jae had been cast for the series. Lee Hye-ri stars as Yoo Jae-yi, the top student of Chaehwa Girls' High School and a hospital director's daughter. When questioned about the reasons behind her decision to take on a role that involved smoking and a same-sex kissing scene, she said that, despite being burdensome in some ways, she really wanted to participate, explaining: \"When I looked into the story, I thought that there were parts that could only be understood when you are in your late 20s. That's why I took courage regardless of my age. It's not easy to participate in a school drama as time goes by, so I became even greedier.\" As for the same-sex kiss scene with co-star Chung Su-bin, Lee Hye-ri commented that she wasn't worried because she thought it could clearly show the two characters' conflicts and obsessions. She also added that Jae-yi was starkly different from her previous, warm and smiling roles. Chung Su-bin said that she auditioned because it was a scenario never seen before in Korea that broke away from the framework of existing dramas. Kang Hye-won shared that she had found the \"girl thriller\" genre attractive and interesting, with Oh Woo-ri adding that the charm of each character was the most important part. ==Original soundtrack== ===Part 1=== ===Part 2=== ===Part 3=== ===Part 4=== ===Accolades=== ==References== ==External links==", "categories": [ "100257668", "100850586", "100850806", "20134663", "20138470", "23118434", "23603337", "26379736", "43593316", "48670899", "63706546", "63707109", "63707111", "73032201", "76441546", "76441555", "8048380", "83219642", "8374092", "87519749" ], "license": "CC BY-SA 4.0", "source_uri": "https://en.wikipedia.org/w/index.php?oldid=1366801916", "content_hash": "", "created_at": null, "updated_at": 1785395871.0, "claims": [ { "id": 33794671, "subject_qid": "", "subject_slug": "friendly-rivalry", "predicate": "release date", "object_text": "2025-03-06", "object_num": 20250306.0, "object_unit": null, "polarity": 1, "qualifier": "", "source_uri": "https://en.wikipedia.org/w/index.php?oldid=1366801916", "source_name": "Wikipedia", "source_tier": 3, "retrieved_at": 1792539270.6845582, "confidence": 0.95, "article_slug": "friendly-rivalry", "span_start": 7, "span_end": 55 } ], "contradictions": [], "confidence": 0.95, "csl": { "id": "enwiki-001366801916", "type": "webpage", "title": "Friendly Rivalry", "author": [ { "family": "Anticloud FZ LLE", "literal": "Anticloud FZ LLE" } ], "container-title": "encyclopegia.org", "publisher": "Anticloud FZ LLE", "publisher-place": "Dubai, United Arab Emirates", "URL": "https://encyclopegia.org/a/friendly-rivalry", "issued": { "date-parts": [ [ 2026, 11, 15 ] ] }, "accessed": { "date-parts": [ [ 2026, 11, 15 ] ] }, "license": "CC BY-SA 4.0", "DOI": "eo1:enwiki-001366801916", "isBasedOn": "https://en.wikipedia.org/w/index.php?oldid=1366801916", "note": "Immutable snapshot enwiki-001366801916" } }
