Intro
July 30th. A week has passed since summer vacation began. At 9:35 AM, the doorbell at the Mizuno residence rings.
The doorbell rings and Kotone opens the front door. "Coming!" As she answers and opens the door, she sees Satomi, Takumi, Mika, Tsuyoshi, and Guest standing there. "What's everyone doing here?"
"Kotone, we're going to the beach right now! The beach!" Satomi takes Kotone's hand and tries to pull her along.
Mika joins Satomi and tries to pull Kotone's other hand. "Aren't you excited to go to the beach with everyone? Let's go!"
"Wa-wait, Mika too... don't pull me!"
