[Sports Today reporter Song O-jung] Good Data Corporation’s FUNdex ranked Lee Sona of TV Chosun’s 'Miss Trot 4' as the No. 1 most talked-about non-drama cast member in its TV–OTT integrated rankings for the first week of March.

Lee Sona’s buzz score during the program’s finale week increased by about 116.9% compared with Season 3 winner Jung Seo-ju. Heo Chan-mi, who placed fourth among non-drama cast members, also registered higher buzz than the Season 3 winner.

Eo You-seon, a researcher at Good Data Corporation, said that attention around contestants such as Lee Sona and Heo Chan-mi ahead of the finale drove the show’s four-week rise in buzz, helping it achieve its highest-ever score.

Coming in second and third were Park Bo-gum for tvN’s 'Bogum Magical' and Lee Su-ji for Coupang Play’s 'Sister Chicken,' respectively. Ahn Yoo-jin, who appeared as a guest on 'Please Take Care of My Refrigerator (since 2014),' placed fifth.

Ranks six through nine went to Choi Hyun-wook of tvN’s 'After-School Teacher Taeri,' Go Yoon-jeong of MBC’s 'Manitto Club,' Kim Tae-ri of 'After-School Teacher Taeri,' and Heo Kyung-hwan of MBC’s 'Hangout with Yoo.' Lee Sang-i of 'Bogum Magical' entered the Top 10 for the first time at No. 10.

Good Data Corporation’s rankings for the first week of March covered TV non-dramas and OTT original non-dramas that aired, were released, or were scheduled between March 2 and March 8, 2026, and included each program’s cast and guests.

To determine the week’s most competitive programs, the buzz analysis examined news articles, VON (Voice of Netizen), videos (clips and shorts), and social media posts and the public’s responses to them. Collected data unrelated to the programs and abusive content intended to inflate buzz scores were filtered out. This methodology yields a more accurate assessment of program competitiveness, with reported accuracy above 97%.
