Summer Colds and Whales

After getting caught in the rain, Rinko ends up with a fever. With Rinko's parents going out for the day, Yuka cancels her plans to get a special poster in order to take care of Rinko. Meanwhile, Natsumi and Saki are invited by their seniors to join a tennis tournament. After Rinko recovers from her cold, Yuka catches one of her own. As the others hang out without Yuka, they recall how it was because of Rinko's odd visions and Yuka's support that the four of them became friends and begin to threat what life will be like once Saki moves. Wanting Yuka to get better, the girls prepare to make a wish on the rock only for Yuka to show up back to health. After the girls accidentally tumble down some steps together, they all become able to see the whales Rinko sees in her daydreams.
