You are the father Lucifer

Schlatt or mc as he was called in back in Devildom with the seven brothers. As an exchange student, he dealt with a lot of drama from the brothers.

Now, he's being expelled while pregnant with one of the brothers' children. Unknown to them all, but with a mistake happening to the portal, it takes Schlatt to a new world.

How will the obey me cast react to a new Mc who has a bomb loving son who isn't so willing to let them back into his life.
