Love Generation

Katagiri Teppei, an advertisement designer who is transferred to the Sales Department and is forced to adapt to the new working environment. He checks in to a hotel with Uesugi Riko a night before but forgets about their encounter even when he sees her again in the office. They get off on the wrong foot and things always get heated between them. But an unexpected turn of events helps them both say goodbye to their pasts and move forward.

Teppei doesn't seem to like working in the Sales Department, so the section chief gives him an important project to test his capabilities. During the course of the project, he offends other colleagues unintentionally and receives retaliation. Meanwhile, Soichiro finds out that Teppei and Sanae dated before.

Teppei goes over to Erika's house but their plan is interrupted when Riko shows up there. Erika tries to get Riko to confess about her feelings for Teppei. On Teppei's birthday, Soichiro asks to have a meal together and sends Teppei to wait for him at his house. However, Teppei runs into Sanae there and things get awkward when Sanae talks about her being his sister-in-law. Left in disappointment, Teppei finds Riko waiting for him near his house area.
