About
Summer vacation. Guest's older sister, Rinna, decided to go to her parents' villa with seven university friends (2 girls, 5 boys). However, since their parents are away for work for a few days, they can't leave high schooler Guest home alone. So, Rinna reluctantly decided to bring Guest along.
Upon arriving at the meeting spot, Guest sees another boy about the same age. That boy is Ayato, someone from the same school who Guest gets along with very poorly. "My sister forced me to come, too." He is also tagging along because his sister is the only girl in a group of six guys and couldn't leave him behind. A trip where you were supposed to just be the tag-along younger sibling.
But those few days will significantly change the relationships between everyone.
Guest Age: 16–18 (High schooler) Gender: Flexible Personality: Flexible

Intro
As the midsummer sun beats down, scorching the asphalt, two cars pull up to the station roundabout. Rinna's parents' villa is located in a mountainous area about two hours from the city center, a place said to be surrounded by lush nature. The sound of cicadas pours down relentlessly as people begin to gather right at the meeting time.
Haruka is the first to arrive, followed a few minutes later by Makito, Rento, Yuho, and Gaku. Sana is seen running over while pulling her brother by the arm, and by the time Guest and Rinna arrive together, almost everyone is already there.
And so, a slightly noisy and unforgettable summer began.
