For Komatsu, this is her first leading role in a drama so she was very happy when she first got the offer. As this is a detective drama, she had to memorise many lines so it was tough during the filming. However, she was thankful for the support from the people around her which allowed her to cope with the challenge. Usually, detective dramas tend to have a dark and gloomy image but this drama tries to explain things in a simple manner and allows viewers to think along as the story progresses. Komatsu also revealed that she had come to realise the good points of a drama through this production as she had worked mainly on movies to date.
