Sarina Tendouji/Relationships

Marina Tendouji & Unnamed Father
Before Sarina was diagnosed with anaplastic astrocytoma, Marina loved her daughter. However after the diagnoses, Marina was heartbroken and her husband kept them separated to ease the pain. As a result, Sarina's parents rarely visited during her stay at the hospital, stopping altogether as her condition approached terminal and they did not come to see her before her passing.

Gorou Amamiya
Likely due to her parents' neglect, Sarina was very attached to Gorou. She once cheekily asked him to marry her and even told him that she loves him in her final moments. When she reincarnated as Ruby, she never forgot about him and would secretly call the Miyazaki General hospital to check on him. When she thought she finally had the chance to meet him once again, she was devastated when she and Akane discovered his corpse during their shoot for their music video in Miyazaki. His death was mainly the factor, added by the fact that it is connected with Ai's that she easily fell into the same dark path as her twin brother.

Ai Hoshino
She adored Ai and was a big fan of her. She spent most of her days in the hospital living a lonely and painful life but because of Ai she gained a light and dreams to become an idol like her. When she reincarnated as her daughter she wanted to savor every moment and always seeks her attention. She would become her drive towards her goal of becoming an idol herself.
