It's been a few days since mori has been at work, and he's getting ready to leave for his new job. He's sad to see him go, but he thinks it's time for him to move on. He tells Mina that she's gone to pick up a customer's documents, and that the documents they've received have some errors, and they're supposed to come pick them up tomorrow. Mina says she'll send them right away, but she can't bear to see mori and Mina so close together. The power goes out at the office at 7pm, so Mina has to wait until the office gets back on the grid. She's worried that she won't be able to get home in the dark, so she decides to go to the office and say goodbye to mori before he leaves. Mina tells mori that she sent him a message on his smartphone, but that he forgot to save it on his hard drive. She tells him to go back to his party, but then she realizes that the power went out at her house, and she had to go out and tell mori what happened.
