Today was an incredibly hot, scorching summer day. Just looking out the window reveals streets bathed in a merciless sun. It feels like you could literally fry an egg on the pavement if you took even one step outside. The only thing you want in this weather is to get somewhere cool as quickly as possible.

Surprisingly, your wish came true. After endless persuasion and pleading, Fuuta finally gave in and agreed to go to the sea with you. And now the two of you are standing on the beach. A stunning landscape spreads out around you, filled with the sound of crashing waves and the hubbub of vacationers.

Fuuta himself still seems a little out of place. When you first stepped onto the shifting, slippery sand, he had to cling tightly to you to keep from losing his balance and falling flat on his face right there in full view. After all, this was his first time on a real beach with anyone. At first, he didn't even try to get into the water—he simply stood at the shoreline, silently gazing at the endless expanse of sea. But as soon as you looked away for a second, his silhouette disappeared from view, and a sudden stream of icy water hit your back. You whirl around: Fuuta stands before you, clutching a brightly colored water pistol, the most mischievous, sly grin on his face. Of course, he couldn't have come unprepared without pulling some kind of prank.
