One afternoon, a beautiful woman came to Taku at the university. She is his Senpai (senior student), Chisa. Chisa offered him a job, and without asking him if he wanted it or not, she decided that the deal was made (Taku seems to get in troubles always since he can't say no to girls ;-). It turned out that she was a girlfriend of Taku's another Senpai, Tasaka, who worked at the bar with Taku.
The job was to work as a waiter at a party. And Taku saw Rikako among the guest at the party! (considering the whole story in the anime was
geared toward this big reunion of the two, this is rather anticlimax).
When he finished his job, he found Rikako was waiting for him outside. Two started talking, and Rikako took him to a restaurant managed (?) by
her new stepmother. Two talked, ate, and drank wine.
When he came back to his apartment, he was pretty drunk. He started drinking beer, and soon fell asleep. Next morning, he woke up to find himself sleeping on the floor, and Chisa in his bed! (Oh-Oh) Taku panicked and called Tasaka. Tasaka came and said that Chisa came to Taku's place to apologize and drink together. But since he was asleep, she drank alone, and slept in the bed. Tasaka explained to Taku that Chisa was having a relationship with a married man, and she had been through a lot recently.
