Ep. 4: Retsuko mengakhiri hubungannya dengan Haida setelah menerima saran dari Manaka.

4

Haida learns from his bandmate that his girlfriend had dumped him for having no career progression. During a drunken night out with Fenneko, Retsuko becomes frustrated about Haida's lack of confidence in pursuing a relationship with her. On their way home, Himuro takes the two to dinner as an apology for splashing a puddle on them, and in their drunken stupor, they complain about Ton. Soon after, Retsuko seeks advice from Manaka, who advises her that she and Haida are incompatible. When Haida takes Retsuko home the day after, she tells him he no longer needs to do so and that she prefers they stay as friends. Using Retsuko's feedback, Himuro reassigns Ton to the "career experience design" department, with his new office being a storage room isolated from the company building. (Source: Wikipedia)
