Lumina was married into the family Kenobi through her husband Zero Cold.

They were firstly united by a strong bond, unknown to them until many years had passed. They had come from the same kingdom, and were childhood friends. Their families shared the same land, the same habits, the same joy and worry, except for Zero Cold's father, that he only saw when he was a young boy.

When Lumina was 8 years old, she was sent to Koguryo, to the cares of the Bear clan, where Lumina's family, the Syng-sa, had many friends. There she met people who played a very important role in her life, teaching her from the Monk ways to the Do trainings, and everything else she has in life. She could not have accomplished many things without the education and love of the Bears.

A long time passed until Zero Cold arrived in Koguryo, being lead to the Bear clan, to learn from the same people as Lumina once did. Being a monk at the time, Lumina taught him of the ways of the Monks, and guided him spiritually and morally, helping him to get used to the new way of life.

However, this relation was superficial, for neither of them recognized each other, and treated each other as newly met. After a short time, Zero Cold left the clan to find a new home within another walls.

His contact with Lumina was small, and became none when she decided to leave the kingdom to experience the life of a Wanderer, spending there many years. This journey was delayed even more, when Lumina decided to have training within a Buddhist Monastery.

Many years passed when she came back to the kingdom, to find her good friend transformed by time and Do training, and many things changed. She fought to accept that. She thought her world was ruined, feeling confined and restrained in her old home.

She was tempted to leave again. However, Zero Cold offered her devotion and compassion. At a later date, a distant relative of Zero Cold came to find them and tell them about their past together. Lumina felt that somehow it was her destiny to have found a lost brother, and that she should not let herself go, for something bigger was waiting for her.

They shared many moments together until the day Zero Cold confessed his love for Lumina.

She realized that she could not move on without him anymore, and they have been together since then.
