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.

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.
