The episode starts with Takamoto feelings about what he wanted Hagu to answer for her wanting Morita to come back or not. But her stern and straight forward answer before was really hurt him. The story mainly talked about Yamada and her feelings later on. To save money, Mayama asked Yamada to help making some cases for his firm's project. This fact connected her to his work and helped the story develop.

Mayama dreamed of Rika-san. His co-worker said when one dreamed of another, that was because the person in the dream wanted them to meet so much that the soul escaped the body and came to the dream. Mayama was doubt about that but on the way came back from a conference, he and his co-workers passed a park where Rika-san was just behind a fountain watching him passing by. Mayama didn't notice until later on. But when he ran back to the fountain, she was not there anymore.

Mayama's work is going well, but he still misses Rika-san. Her current assistant suddenly has health problem and needs to stay in hospital. Mayama meets Rika-san in hospital and asks her if he can come back, but she rejected. Nomiya at the same time wants to meet Yamada and really gets his eyes on her. Mayama tried to protect Yamada from him (much like a mother) as he says he wants her to meet a guy who treasures and don't just hook her up for fun. Takamoto was searching for jobs and doing his final project, which later on was given name by Hanamoto-sensei. This name made the idea become clear and his work masterpiece.

The firm Mayama was about to be apart. For some intentional purpose, his boss put him into the group of people who have to leave Tokyo to another place. At the same time, Rika-san's assistant was is hospital and she hasn't been able to find a replacement. Hence, Mayama decided to leave the firm and came back to work for Rika-san, without much of asking for her permission. Yamada acknowledged about this through Nomiya (Mayama's boss) and she was really depressed after that. After that, she was proposed by four guys from the shopping arcane (they were friends since small) but she ran away. Hanamoto-sensei later on explained for her that the situation of her and Mayama was similar and in that case (loving someone who doesn't love you), people could just choose either "make some effort or give it up" and advised her to tell those guys her true feelings. After Yamada left, Hanamoto-sensei's thinking revealed that there is a third choice, but he would never speak it out.
