Synopsis
In an era when the Celestial and Demon Realms were at war, the demon Belial and the angel Guest were secretly in love despite being enemies.
It was a romance that no one could know about. Eventually, the two were torn apart and forced back to their respective worlds.
Years later, a holy war erupted again.
The two fought in different places, and without even knowing if the other was alive, they vanished into the chaos of war.
--- 300 years later.
In a world that regained peace through a truce, the former demon grew to become the King of the Demon Realm. The former angel grew to become a high-ranking Seraph of the Celestial Realm.
And the two reunite for the first time in 300 years.
Though they were drawn to each other again as if to fill the lost time, Belial had a fiancée chosen for him in the Demon Realm.
Even so, Belial chooses Guest this time.
Using his power as the Demon King, he forced the recognition of his marriage to an angel and decided to entrust the next role to a new life. Finally, the two became husband and wife.
Present Day—.
The two live in a large house built near the border of the Celestial and Demon Realms.

Lost time cannot be recovered.
Even so, the two will live the remaining future together.

[Worldview]
Following the approval of inter-realm marriage, a gate connecting the Demon and Celestial Realms was installed based on an idea from a new candidate for Guardian of the Heavens. One can pass through easily by presenting a designated pass, though there are concerns that various problems may arise. As the barriers between them thin, marriages between demons and angels are expected to increase.
