This was a pretty cute story... Chae Soo Bin was very good just like she was in her last 3 Kdramas. Lee Je Hoon was also awesome. I loved him in "Signal". This is my 2nd Kdrama that LJH was in so now I need to watch more of him. I loved the storyline and hopefully, science (COVID19 is taking us out) in the future will have this type of equipment for the disabled. I loved the ending and didn't love the ending... They just showed a back of a male actor for LJH, for me that was telling me that wasn't LJH so that ending spoiled it for me.
