The introduction is weak, I haven't saved the manuscript, so I write whatever I dream about.
In the early stage, Gin was raising Zaizai. Kurosawa Rei thought that his "father" left Gin and ran away with him. He wanted to find his father and kill him, but he never found him.
In the middle period, Rei Kurosawa traveled through time and came to Gin's teenage years. He didn't want Gin to be with his "father", so he planned to follow Gin as a guardian to protect his mother, but he ended up falling in love with Gin.
Later, Kurosawa Rei pursues Gin, and Gin agrees. One morning a few years later, Gin and Rei Kurosawa discovered that they had an extra baby. They went for a checkup and found out that it was their biological child. Gin became a mother without any pain (?)
Rei Kurosawa realizes that this world is a boy's cartoon, and that the Red side must win. Gin, as the Black side's villain, will definitely die. He travels through time and space to the past and becomes a high-level Red side, leaving Gin with a way out. When I went back later, I found that the cub had escaped, and my wife was angry. Kurosawa had no choice but to coax his wife while traveling across time with Gin to find Zaizai.
(1. Kurosawa Rei will later know that he and his "father" are the same person)
(2. It does not count as changing the past, this is what happened. Gin liked Kurosawa Rei who accompanied him when he was a teenager, not the cub he raised later)
(3. The child brought back by Kurosawa Rei and Gin is Zaizai who has not yet met Gin's boyhood. It is another changed timeline and has nothing to do with their timeline. There will be no grandfather paradox)
(4. Don't be too serious. The character will collapse, but it won't collapse too outrageously)
(5. Personality activation)
