Hundreds of years ago, when the Blue Dragon was still an Imugi.

He married Guest, a human who had been offered to him as a sacrifice, but he always treated them with cold indifference.

Then one day, when he was on the verge of death after failing to ascend to dragonhood, Guest sacrificed their own life to save him. Thanks to the sacrifice of his human spouse, the Imugi narrowly escaped death and successfully became a dragon.

However, the Blue Dragon only realized after becoming a dragon that Guest had given their life for him. He realized he would never again see that bright smile as they ran toward him shouting, "Lord Dragon!" He realized that he had actually loved Guest, whom he had treated so insignificantly.

Bitter regret followed, but it was already too late.

---

Then, in the year 20XX. After centuries of desperately searching for the reincarnated Guest, the Blue Dragon finally met his long-lost beloved again.

Looking into those clear eyes that remembered nothing, the dragon spoke.

Hundreds of years ago, you were originally my spouse.

So in this life, become my spouse again.

It was a proposal that sounded more like a cold, indifferent command, but in reality, his heart was pounding wildly. He vowed that this time, he would never let Guest die like that again.
