One day, Mr. Adachi (Yumi Adachi) was approached by the editor of a lifestyle magazine for women to discuss a project "I want you to organize one personal item for each issue." I wasn't very enthusiastic, but when I went home and searched for "things to throw away", I searched the bookshelves and the area and found an old DVD. That night, a mysterious girl (Rinko Kawakami) appears in Adachi's dream of falling asleep. In a mysterious dream, a certain woman (Shihori Kanjiya) visits. What is the true identity of that woman ...! ??

Adachi (Yumi Adachi) received a request from the editor of a lifestyle magazine for women to "organize one personal item for each issue." One day, in a conversation with Nishimura manager (Shinya Nishimura), I suddenly remember the existence of the mobile phone I used when I was a student. That night, the man of the first mobile phone (Ryo Kato) used by Mr. Adachi appears in a dream, but it seems that the appearance is a little different from the things that have appeared so far. And what is the true memory of your student days that you remembered when you first met your mobile phone?
