In a hot summer day, after receiving a watermelon from the Hidamari landlady, Yuno and her friends make a visit to a local swimming pool, where Yuno's inability to swim and fear of water is revealed. Meanwhile, Yoshinoya, the Hidamari landlady, and the Principal spend their time together in a school swimming pool.

To Yuno, Miyako, and Sae's surprise, Hiro receives a love letter from a 3rd grade classmate. After hearing the news, Hiro's friends can hardly concentrate on the class as they are very curious about the love letter.

However, Hiro's friends look up to her for her maturity.
