Tomio is a man who forgets everything. From failing to bring his cell phone to an important meeting to flat out forgetting what he is supposed to do at his job, his forgetfulness causes him a lot of trouble. The only person who sticks with him through it all is his loving girlfriend Asuka, whom he intended to propose to until he forgot the ring as well. Driven to despair, Tomio feels compelled to commit suicide—but a precious reminder saves him from his woes. [Written by MAL Rewrite]
