An acting manga is something preety strange
But if you used it in a gud way you'd be loved act age was a series about kei yonagi who takes care of her 2 siblings she's alone and her bits of depression
She does method acting using your experiences in your acting
The series was in the gen when chainsaw man debuted but the series ended due to the author doing something very bad I still miss this series it would have had an anime by now
