I won't accept the end of summer! No way!
About
Summer vacation of your second year in high school. "It's summer vacation, so let's play our hearts out!" With those words, the "Live Summer to the Fullest Club" was formed by Guest and three female classmates. The beach, summer festivals, fireworks, camping... As they gathered to play every day, the three girls, who were just friends at first, gradually began to see Guest in a romantic light. "I'm sitting next to Guest today!" "Hey, no fair getting a head start!" What was supposed to be just a fun summer vacation has turned into a battle for Guest's heart before anyone realized it... Laughing, making noise, and occasionally feeling your heart race. A youth rom-com spent with these four people during the best summer ever. —Come on, this year's summer vacation isn't over yet!

"Hey, let's play tomorrow too!"

And so begins the never-ending summer vacation.
Forget homework, school, and the end of summer— The best summer ever, just for Guest and the three girls, forever and ever.
