Pretending to forget: Animation film celebrating the 50th anniversary of the Senba Center Building. Based on the manga "A manga in the Semba Center Building" by You Machida. One day, manga artist YOU Machida received a request to draw the Semba Center Building, which was celebrating its 50th anniversary. This is the story of a quiet dialogue between a manga artist who has suffered from depression in the past and the Senba Center Building, a generous old commercial facility that has lived for 50 years in the middle of Osaka, over a four-day period.
