Hoshino Aqua, whose full name is Hoshino Aquamarine, was an obstetrician in his previous life, Goro Amamiya. Now an active actor, he carries the soul of a top graduate from the University of Tokyo's medical school. His one and only favorite idol in his previous life, Hoshino Ai, is also his biological mother in this life. She died as a result of the schemes of his biological father, Kamiki Hikaru. The irony is that Aqua himself once died at Kamiki Hikaru's hands, while serving as Hoshino Ai's attending physician. He could just about ignore the pain of being ambushed and falling to his death from a cliff, but his mother, Hoshino Ai, had her brief life brought to a close by a ceremony her father had planned, losing her life in front of the children she loved most. Her soul transformed into all things under heaven and vanished from this world forever.
The rage of losing his idol and the pain of losing his mother torment him every moment, reminding him: Ai died right in front of you. Find the killer. It's your responsibility. And the patient you cared for in your previous life, Sarina Tendouji, died at twelve. You couldn't save her either. To say nothing of a happy life, you don't even deserve an ordinary one.

High school detective Shinichi Kudo was on a date at an amusement park with his girlfriend, Ran Mouri, when he stumbled upon the secrets of a crime syndicate. They forced him to take the lethal poison APTX 4869, but by some stroke of luck, he didn't die. Instead, his body shrank, turning him into a child. When he returned to the home of his family and friends, Ran nearly discovered him. In a panic, he took the alias Conan Edogawa. For his own safety, he is still searching for an antidote that will turn him back into an adult. While tangling with the Black Organization, an unexpected incident occurred: a talent scout discovered him, dragging him into show business against his will. In a world where fame is everything, it was a good thing that nobody would notice how many cases he quietly solved. Unfortunately, it seemed he had inherited a little of Yukiko's talent for acting, and several agencies began fighting over him. Just then, a boy with black stars seemingly dancing in his eyes pulled him away and ruffled his hair. "You've had a rough time. You did great."
A few days later, the boy came to visit again and casually asked, "By the way, is your dad Shinichi Kudo?"

After endless conflict and despair, Hoshino Aqua still chose the most painful, most tormenting path.
He no longer needed anyone, whether they understood him or not, whether they loved or hated him.
But he still worried about his sister, Hoshino Ruby, his only blood relative in this life. Distance hurt and felt cold, but it was effective. Only then could she stop turning back to look at him as she walked her own path and shine onstage.
He had once had happy days, but those were nothing more than his selfish fantasies and a betrayal of love, weren't they?
Not long after, he met an exceptionally clever child. The boy's calm, unwavering reasoning was unmistakable, but the innocence and childishness he showed in everyday life also told Aqua that he couldn't drag him into this. Like Sarina, he was only a child.
But the DNA test Aqua took on a whim, refusing to believe it, clearly told him: Bring him along. The boy has the ability. With him, your path won't be lonely and difficult anymore.
**
Conan Edogawa and Hoshino Aqua traveled together, but with every step Conan grew more uneasy. He was clearly walking beside a potential criminal. Yet Conan had no intention of stopping. If asked why, he couldn't say. Perhaps it was the hesitation and struggle in the boy's voice before night fell on the day they sat talking, the regret and self-abandonment that surrounded him after dark, and the fake smile he wore the next morning.
But Conan wanted to tell him: Shinichi Kudo is a detective, and Conan Edogawa is a person. They are one and the same.
So stop wearing that calm expression. A detective's eyes don't lie. Your heart is crying.

As long as Hoshino Aqua was alive, he had the power to turn the filthy underworld behind this stage upside down. But Aqua knew he was just an ordinary, good-looking man with no particular talents, so he had to make use of everyone around him who could be of use.
He wanted revenge. It was all he had left to live for. If he could make his sister happier, he would go through fire and water for her, especially since she bore a faint resemblance to Sarina, the patient he'd cared for in his previous life. So when Conan Edogawa left the next morning, Aqua could tell that his acting had easily won the boy over. He wanted to laugh, but the child's clear, reassuring gaze weighed on him until he could barely breathe.
He had used a detective with a bright future ahead of him.
When had he changed from a young man with a pure dream of saving lives into someone so dark and reckless?
**
I know full well that you're using me. But that's okay. I can see how much you hate yourself for it. If I can bring you back to the right path, Miss Akemi will surely be glad in heaven.

- It had been like this every moment of his life, from childhood to adulthood and even after his reincarnation. After all, he was simply a weak, helpless person.
