According to an insider, "Lee Tae Im was receiving lessons on swimming in the ocean and becoming a diver. Recently while filming at the cold winter ocean, she was asked, 'Isn't it cold. Are you okay?', but she suddenly got angry and cursed harshly. Because it wasn't a situation that would have provoked her, everyone was surprised by her actions, and the filming was stopped." With this, she has left only a month into her joining the program. 

Another source affiliated with the show elaborated, "Yewon asked her 'Aren't you cold' after she came out of the water during the recording on February 24th. But suddenly Lee Tae Im started cursing at her and asked her why she was speaking informally to her, and the filming atmosphere became bad. At the time, Yewon had not used the informal speech with Lee Tae Im, but Lee Tae Im started to raise her voice and started to throw curses at Yewon, shocking everyone on set... Lee Tae Im had also been scheduled to film on the 23rd too, but she didn't show up. So that and her cursing outburst [the next day] are what I believe led to her leave from the program."

One insider also revealed that because this happened during filming, her outburst was caught on tape. "I saw a portion of the problematic filming. The situation seemed quite severe. As there is a video that caught the happening, it shouldn't be hard to determine the truth about what happened."

When Star Empire, Yewon's agency, was contacted to elaborate, her reps cautiously stated, "After the reports came out, we have been receiving a flood of phone calls, but it is hard for us to say. It's true [Yewon] heard curses from [Lee Tae Im], but they did not argue. As Yewon is younger than Lee Tae Im, it wasn't her place to talk back. So she didn't argue and the situation just passed over."

Lee Tae Im's agency as well as MBC are however insisting that the actress left the show because of her health. The actress's agency commented, "She felt something was wrong with her health while filming for the drama and the variety program, so she was hospitalized last month after finishing up a filming session for her variety program. It was just simply fatigue and symptoms of a cold, so it wasn't severe. She got better and was discharged from the hospital and returned to filming her drama today. She is currently filming without any problems."

In regards to her leave from her variety program, her agency commented, "She came to leave the show suddenly, but we have wrapped it up with the staff of the show without any conflict." 

MBC also remarked, "The reason for Lee Tae Im's leave is due to her health. We have nothing else to say other than this."
