The manga "Cannot Play!", which depicts the work behind the scenes of a TV show, has decided to be adapted into a TV animation! ! The original author, Kana Mafune, currently works at BS TV Tokyo. The stories told in her manga "Cannot Play!" and "Cannot Play! Deep" are based on her experience as an assistant director at TV Tokyo. I have a vague idea of it, but I only have a limited understanding. What is the real work of an "assistant director" like! ?
