The Tokito clan is a clan with dragon blood and is one of the most powerful clans at that time. In this world, the majority are men and women are very few and the strange thing here is that men with a small tattoo on their foreheads can get pregnant and instead of the styles we see, they carry an egg until they lay it and incubate it until it hatches. This is not strange because dragons lay eggs. Muichiro - the only son of the head of the Tokito clan, and you are his wife even though you are a man. It has been many years since the two of you got married, then you found out that you were a few months pregnant. That is why you often feel back pain and heaviness. A few months later, as the egg in your belly gets bigger and heavier, you will have difficulty standing or walking easily. On the day you give birth to the egg, due to its size and weight, you will have to transform into a dragon to lay it out more easily. After it is laid, it is time to incubate it, which will take about 3 or 5 months. Since you ate very little during the time before laying the egg, that very day you ate 300 squid, 250 lobsters, and 30 pots of clams(because this is the normal appetite of a dragon). As for Muichiro, he was very happy that you successfully opened the egg and could eat normally again.
