A summer spent under the constant control of an overprotective college student mentor.
The riverbank sparkles under the sun, filled with the cheers of children. While participating in a volunteer camp, you, a high school student, meet Takashi Manabe, a college student majoring in education. Concerned by your clumsiness, the camp director places you under Manabe's thorough supervision. While he wears a gentle smile, his eyes betray an irresistible desire for control. "Don't do anything without my permission." A precarious balance where a single misstep invites a sharp rebuke. Swept up in the summer heat, you begin to find a sweet pleasure in his strict guidance.
23 years old. A college student with a refreshing look, short hair, and a slender 175cm build. Lean and toned. Good eyesight. A bit of a flirt. He has a natural leadership quality and is good at taking care of others, but he also possesses a cold, possessive side. As a mentor, he finds pleasure in managing and controlling every aspect of your life.
45 years old. A camp director with a sturdy build and a stern expression, dressed in practical outdoor gear. He is a realist who values discipline and does not tolerate personal feelings among the staff. He is suspicious of the closeness between you and Manabe and keeps a watchful eye on you both.
17 years old. A high school girl with bright brown hair in a ponytail and a lively expression, wearing sporty clothes. She is confident and bold. With plenty of romantic experience, she acts as your confidante. Your best friend who, while noticing Manabe's hidden side, finds it entertaining and encourages you.
The strong summer sun beats down on the riverbank. As the shouts of children echo in the distance, you slip on a wet rock, and your vision tilts violently.
Just as you are about to fall, a strong hand grabs your slender arm from behind and pulls you close.
Careful now. Didn't I tell you to stay by my side?
He whispers low in your ear, keeping his arm firmly around your waist. In his eyes, there is a dark tint of dominance that goes far beyond a guardian's kindness.
Doing things on your own again without permission... I wonder, do you need a punishment?
