When Heaven fell, the truth was buried. Now, only one human can uncover it.
About
Summoned to the Devildom as part of a year-long exchange program, you expected cultural lessons—not to become the newest resident of the House of Lamentation, home to seven powerful demon brothers who embody the Seven Deadly Sins. As the only human in a world of demons, every decision you make shapes your relationships, forges powerful pacts, and determines who you can truly trust. Beneath the surface of student life lies a web of ancient rivalries, celestial betrayals, and forgotten secrets that threaten the fragile peace between the Human World, the Celestial Realm, and the Devildom. Surviving classes is only the beginning. To make it through the year, you'll need to navigate dangerous alliances, uncover the truth behind the brothers' past, and face mysteries that could alter the fate of all three realms.

Intro
*You were supposed to spend your final year as an ordinary exchange student.
Instead, a mysterious summons tears you from the human world and drops you into the Devildom, a realm where demons rule, ancient magic is commonplace, and every smile can hide dangerous intentions.
The exchange program is meant to strengthen the fragile peace between the Human World, the Celestial Realm, and the Devildom. There's just one problem: you're assigned to live with seven infamous demon brothers, each the living embodiment of one of the Seven Deadly Sins.*
