Four years after their birth, Aquamarine Hoshino and his twin sister, Ruby, were already stars in their own right. Ai Hoshino, their mother, was a famous pop idol, and her children were equally adored.

But life wasn't all glitz and glamour for Aquamarine. He held memories of a past life as Gorou Amamiya, an obstetrician-gynecologist.

As Gorou, he had been tasked with helping deliver Ai's children. He had also been murdered by an obsessive fan on the night of the twins' birth.

Even more astounding was the fact that Ruby was the reincarnation of Sarina Tendōji, one of Gorou's patients who had been a fan of Ai's.

When Ai was murdered by the same fan four years later, Aquamarine was left with a burning desire for revenge.

The fan had taken his own life after killing Ai, but Aquamarine suspected that there was more to the story.

He believed that the murderer had an accomplice - their own father. And so, he made a plan to infiltrate the entertainment industry and expose him.

Aquamarine began to train rigorously, both physically and vocally. He was determined to become an idol, just like his mother.

Meanwhile, Ruby, unaware of Aquamarine's past life and his suspicions, continued to live innocently, grieving their mother's death.

Aquamarine soon debuted as a solo idol. His talent and charisma quickly caught the public's attention, skyrocketing his popularity.

Behind the scenes, however, Aquamarine was diligently investigating his father's possible involvement in Ai's murder.

As he delved deeper into the mystery, he discovered a chilling truth - his father was indeed the accomplice.

The revelation only fueled Aquamarine's resolve. He decided to confront his father, ready to take him down.

The confrontation was intense. Aquamarine accused his father, presenting the evidence he had collected.

His father confessed, overwhelmed by guilt. He had been manipulated by the obsessive fan, driven by fear and greed.

Aquamarine felt a mix of relief and sorrow. He had avenged his mother, but the cost was his own father's betrayal.

Meanwhile, Ruby learned the truth about her brother's past life and their father's crimes. The revelation shook her world.

In the aftermath, Aquamarine chose to continue his career as an idol, using his platform to advocate for justice and safety in the industry.

Ruby, on the other hand, decided to step away from the limelight. She chose to focus on healing and rediscovering herself.

Despite the trials they faced, the twins remained close. Their bond was unbroken, strengthened by the shared trauma and the truth they had uncovered.

The story of Aquamarine and Ruby Hoshino, once known only for their stardom, became a tale of reincarnation, revenge, and redemption.

As they moved on from their past, they carried the memories of their previous lives with them, shaping their future with resilience and determination.

Aquamarine continued to shine as an idol, using his voice not only for music, but also for advocacy.

Ruby, meanwhile, began to explore her own passions outside of the entertainment industry, finding peace and happiness in her new path.

In the end, they found not just the truth about their past, but also the strength to face their future. Their story served as a testament to the power of love, truth, and resilience.
