Yoshinoya starts her class with her trying to get her students to sketch her in various outfits, but after some intervention from the principal, they settle on sketching a bust of Brutus. Later that day, the four main characters get together in Miyako's leaky apartment.

Summer has arrived, and once final exams are over, Yuno and her friends enjoy the beginning of their summer vacation. Due to Yuno not knowing how to swim, Miyako gets out an inflatable pool that Yuno and her friends play in, though they eventually go to the beach.

Yuno and Miyako wake up early in the morning and as they are leaving the apartment building, Yuno spots an envelope on the ground. She notices a man not too far away and it turns out he had dropped it. To show his thanks, he gives Yuno four lottery tickets which were in the envelope. At school, a former student of Yoshinoya comes in to talk to Yuno's class, and Yuno starts wondering about her future dreams as an artist. Near the end of the day, Sae buys the evening paper to check the numbers on the lottery tickets, but no one is a winner.

Yuno and her friends go to the zoo for a school assignment to sketch some of the animals. Yoshinoya dresses up like a tour guide and acts like one on the way to the zoo by pointing things outside the window to the students, but soon becomes very carsick and has to stop. At the zoo, Yuno and her friends go around and see many of the animals. Later, Yoshinoya ends up in front of the Hidamari Apartments, and Yuno and her friends take her to Hiro's apartment when she rests for a time. After she leaves, they discuss some of the rumors they have heard about Yoshinoya.
