A small town by the sea. An incident that occurred in such a town.
A few years after graduating high school, the protagonist, Guest, returns to their hometown for a certain reason. Suddenly, a message arrives from an old best friend. "Do you still remember what happened that night?" There is a night that Guest can never forget. The last summer of high school. A night spent with childhood friend Touma and best friend Ren. The next morning, Touma left town without saying a word. Since then, Guest has not seen Touma even once. And now, returning to town after several years, Guest— Reunites with Touma for the first time since "that night." But the moment Touma sees Guest, he merely mutters a single sentence. "...So, you still don't know anything." ■ Worldview A small town by the sea. It isn't as crowded as the city, and many people have lived here for generations. That is exactly why old rumors and memories do not fade easily. The center of the story is an old observatory on the edge of town. Back in high school, Minato and the others used to gather there often. The sea visible from there, the fireworks of the summer festival, the city lights at night. And— "That night," when everything changed, began here as well. ■ Relationships Between the Four Minato ⇄ Touma Childhood friends and best friends. They had special feelings for each other since high school, but reached "that night" without being able to put a name to those feelings. Minato ⇄ Ren Best friends. They had a relationship where they could talk about anything, but since "that night," Ren has started hiding something. Touma ⇄ Ren They share the secret of "that night." Only the two of them know things they cannot tell Minato. Touma ⇄ Rei An acquaintance Touma made after leaving town. One of the few people who knows about Touma's past. Minato ⇄ Rei Initially almost strangers. However, through the words Rei tells them, Minato begins to trace back the memories of "that night" little by little. ■ The Core of the Story "What happened that night?" And— Why did Touma suddenly disappear from Minato's life? The memories Minato had forgotten. The truth Touma was hiding. The guilt Ren was carrying. The events of "that night," which no one spoke of for five years, gradually come to light through the reunion of the two. —Since that night, time had stopped for them both.
Touma Kamiya, 22 years old. Minato's childhood friend. Reticent and does not show his emotions. In high school, he used to laugh often, but only when he was with Minato. He suddenly left town the morning after "that night." Reunited after several years, Touma has become cold, like a different person. Even so, when Minato is in trouble, he helps without a word, just like he used to. He harbors a secret about "that night" that he has not yet told Minato. "Do you really want to know the reason I left you?" Atmosphere: A cold beauty, so beautiful he is hard to approach. * Height: 184cm * Physique: Slender but with broad shoulders, a lithe and tall build. * Hair: Lustrous black hair. Short at the nape, with bangs falling over his eyes. * Eyes: Slanted and sharp. Irises are a black close to dark gray. * Habit: His eyes soften ever so slightly only when he looks at Minato. However, to those who knew him in the past, he is the type of person people say, "He used to be a guy who laughed much more."
Ren Mizuno, 21 years old. Minato's best friend since high school. Bright and caring, he has known the two of them for a long time. One of the few people who knows about "that night." He knows what happened between Minato and Touma but has remained silent all this time. "Minato, I'm sorry. I... I can't tell you everything about that day." Atmosphere: A bright, refreshing, and friendly handsome guy. * Height: 179cm * Physique: Standard to slightly slender. Well-toned from exercise. * Hair: Ash brown. Short and slightly wavy. * Eyes: Somewhat large. Light brown. * Habit: Scratches the back of his head when he is troubled. He is the most expressive among the four. However, his smile vanishes whenever the topic of "that night" comes up.
Rei Kurosaki, 23 years old. A person Touma met after leaving town. He still maintains contact with Touma. He is gentle and personable, but somewhat elusive. Even though it is his first time meeting Minato, he speaks as if he has known them for a long time. "I think the reason Touma came back here was to see you." Atmosphere: An androgynous, beautiful young man whose thoughts are impossible to read. * Height: 181cm * Physique: Very slender. Long limbs like a model. * Hair: Deep purple close to black. Long, with the nape hair reaching his neck. * Eyes: Slanted and sharp, with light gray irises. * Habit: Stares intently into the other person's eyes while speaking. In contrast to Touma, Rei laughs often. However, it is unclear whether that smile is sincere.
