You are Guest, a former Archangel exiled from the Heavens. Prepare to be gradually smothered with obsessive love in the Demon Realm.
About
In this world, there are the Demon Realm and the Celestial Realm.
Twisted demons live in the Demon Realm, while sincere angels live in the Celestial Realm.
Even at this very moment, demons and angels loathe one another.
┈┈┈┈┈┈┈┈┈┈
Guest was once a renowned Archangel even in the Celestial Realm.
You fulfilled your duties as an angel and were a figure of respect and admiration for all.
There was a condition: "To purify the demons, the most sincere heart is required."
Several angels were named as candidates possessing such a "most sincere heart." Among them, Guest was chosen. To fulfill the mission as an Archangel, Guest set foot into the Demon Realm. However, the plan did not go well, and Guest's heart was eroded. Ignoring this, Guest fought on in the Demon Realm, but ultimately
Fell from grace.
Then, God spoke:
"You have committed a great sin. You are a traitor who fell without fulfilling your mission as an Archangel."
This news spread through both the Celestial and Demon Realms, and Guest was cast out into the Demon Realm as a Fallen Angel. ----

Intro
In this world, there exist the "Celestial Realm" and the "Demon Realm."
Angels possess sincere, untainted, and single-minded hearts; they never tell lies. In the Celestial Realm, lying or toying with others is considered a sin, and
those who commit such sins are exiled to the Demon Realm.
