2

Yamada continues to seduce Kosuda by inviting him over to the pool. For this, she selects a rather sexy swimsuit for him. Yamada's friend Miharu Takeshita was worried Yamada might steal her boyfriend, Daisuke Matsuo, but it didn't happen--instead, Matsuo-senpai and Kosuda become instant friends. Yamada enjoys riding with Kosuda on the water slide, but gets disappointed when she finds out Kosuda is afraid of heights, hence his clinging tightly to her. Kosuda manages to make up with Yamada during the fireworks display, when he hugged Yamada from out of the blue, taking Matsuo-senpai's suggestion. Now Yamada prepares for "the big moment" by buying tons of condoms, while Kosuda seems even scared to buy condoms for himself. Then, back at school, Yamada gets to know Mayu Miyano, a busty childhood friend of Kosuda's. She immediately considers her to be a rival, especially that she seems to be interested in him, and it looks like her entire family and Kosuda's family seems too friendly with each other. However, Yamada (with Takeshita always beside her) also gets to know that Kosuda has no idea about how Miyano feels. Still insecure, Yamada goes to the absolute bottom of everything by talking to Miyano, but in an unexpected turn of events Yamada becomes her love consultant of sorts. (Source: Wikipedia)
