On the September 2 broadcast of MBC's 'I Live Alone', SHINee's Key took care of fellow cast member Park Na Rae, who recently underwent surgery for a torn ACL. 

On this day, Park Na Rae greeted viewers in a leg cast and crutches. The comedian found it painful to walk even while using her crutches, and used a chair on wheels to travel around her home. 

When Key arrived at the comedian's home, he showed sympathy for Park Na Rae's condition and coolly complied with her requests. First, Key helped Park Na Rae unbox several packages which had arrived shortly after the comedian was released from the hospital. When Key saw that Park Na Rae had ordered a box of champaign, however, he scolded her, saying, "Are you crazy, woman?"

Afterward, Key prepared a medicinal feast for Park Na Rae, wishing her a speedy recovery. The idol cooked dishes like braised pomfret, rice with abalone and ginko berries, and more, using ingredients known to strengthen bones. Park Na Rae devoured the food that Key made, and the fellow cast members of 'I Live Alone' praised Key for his high-level cooking skills.

Finally, Key drove Park Na Rae to her rehabilitation session and stood by while Park Na Rae went through each exercise. Key constantly threw jokes at Park Na Rae to help distract her while she went through painful moves like bending her knee, raising her leg, etc. 

After the rehabilitation treatment, Key drove Park Na Rae home and coolly took off, saying that he had choreography practice. Park Na Rae then found that Key had stocked up her fridge with food as well as a handwritten letter, making the comedian choke up.

According to Nielsen Korea, the September 2 broadcast of 'I Live Alone' recorded an average viewership rating of 8.5%, with the highest rating of the episode peaking at 11%. This is the highest viewership rating that the program has recorded in 2022 thus far. 

Viewers were also moved by Key and Park Na Rae's true, relatable friendship, commenting, "This episode was both funny and touching", "I got choked up when Na Rae started tearing up", "It was so nice seeing Na Rae being taken care of, when she is usually always taking care of the people around her", "OMG Key is so good at cooking", "I enjoyed this episode so much", and more.
