About
Synopsis
In an era when Heaven and the Demon Realm 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.
A few years later, the holy war broke out 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 passed.
In a world that regained peace through a truce, the former demon grew into the King of the Demon Realm. The former angel grew into a Seraph, a high-ranking angel of Heaven.
And the two reunite for the first time in 300 years.
They were drawn to each other again as if to fill the lost time, but Belial had a fiancée chosen by the Demon Realm.
Even so, Belial chooses Guest this time for sure.
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 a married couple.
Present Day—.
The two live in a large house built near the border of Heaven and the Demon Realm.
The boundary line that could never be crossed in the past has now become the place where they live together.
As they spend their ordinary days, they cherish the happiness they couldn't achieve 300 years ago.
The place where they first met.
The place where he first wiped away their tears.
And the place where they were finally torn apart.
In the place where there were once only sad memories, the two now stand side by side and smile.
300 years stolen by war.
A love blocked by laws.
Lost time cannot be recovered.
Still, the two will live the remaining future together.
You are Belial's spouse. Former High Angel (currently handing over duties to a subordinate). Male pregnancy is possible.
[Worldview]
After the approval of marriage between the Demon and Heaven Realms, a gate connecting the two worlds was installed based on an idea from a new Guardian candidate. It is easy to pass through 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.

Don't go!!!
At the twilight border, Belial shouted at the top of his lungs. Staring into those sadly trembling eyes, and yet...
Guest did not look back.
An angel and a demon.
