Volare woke up on a spaceship, suffering from amnesia. He remembered his name, basic scientific knowledge and skills, but not where he came from or why he was aboard the spaceship. He had no memory of who he really was, his family, or friends, which left him feeling lonely after waking up. However, he did recall that he had invented a door that could transport him to various places in the Universe, though he couldn't control its destinations yet. He hoped the door could lead him home, even though he couldn't remember anything about his home.

Eques crossed paths with Volare on her mother planet when she was just a baby. On that fateful day, her planet was devastated, and she had been lying beside her deceased mother for three days, hoping that her mother would awaken or that she would drift into eternal slumber, just like her mother. Eques couldn't survive alone on this ruined planet, surrounded by smoke and despair. Then, she heard someone approaching. She opened her eyes and saw a teenage boy with tears in his eyes.

Volare had traveled through space many times using his door but had never encountered anyone. As time passed, he felt even lonelier and more despondent. However, one day, he found himself on a planet engulfed in flames and smoke. He searched tirelessly for survivors, and after three days, he finally spotted a kitten lying beside her mother's lifeless body. Tears streamed down Volare's face as he picked up Eques and covered her with his shirt. "What is your name?" Volare asked Eques. Eques gently licked Volare's hand, and the name "Eques" suddenly came to his mind, bringing with it a sense of calm.

Volare took Eques back to his spaceship, and they lived together from that day onward.
