Star instructor Lee Do, who suspended his lectures three weeks before the CSAT, became the first contestant eliminated from the variety show "Devil's Plan: Dead Again."
In Episode 1 of "Devil's Plan: Dead Again," released on the 10th, Lee Do faced off against Jaejae in a one-on-one match and lost.
In a post-match interview, he expressed regret for failing to achieve his goal of "not being eliminated." Having played multiple games without ever making an impact, he accepted the result and said, "I will grow so that I can win someday."
Earlier, at the press conference on the 5th, Lee Do described "Devil's Plan" as a "dream stage." He revealed that he had enjoyed programs by PD Jung Jong-yeon since childhood and had approached PD Jung at a Netflix event last year to request an appearance. He said he even disclosed his CSAT scores, asking them to consider him for the next season.

Lee Do's attendance at the press conference came one week after he announced the suspension of his lectures. On the 29th of last month, he informed students that due to health issues, it would be difficult for him to complete his Korean Geography and World Geography lectures for the 2027 academic year CSAT preparation. Following his appearance at the press conference, he opened a personal YouTube channel on the 7th to promote his variety show participation, drawing criticism from students.
Online lecture provider Etoos apologized to students on the 9th, stating that although they had coordinated filming schedules with Lee Do, he was unable to complete the promised lectures due to instructor circumstances. Lee Do's Q&A board was made private, and on the 10th, all 17 of his existing courses were removed from the instructor profile page.
On the 10th, Lee Do posted a handwritten apology on social media, acknowledging responsibility for failing to complete his lectures for two consecutive years. He stated, "I prioritized other activities without finishing what I was supposed to do as an instructor," and announced that he would suspend broadcasting and personal content activities until his health recovers.
Lee Do, a graduate of the Department of Geography Education at Seoul National University, appeared on Netflix's dating reality show "Born Solo but Wanting Love" and MBC's "Omniscient Interfering Viewpoint" last year.
