After being summoned, I'm back home again.

20 years after Aiden was summoned to a fantasy world with his friends, he now returns back home, to Earth, to change his summoning from even happening. Why? Ever since he was summoned, his life was hell and his friends were killed. He's going back to change that once and for all... even if it means destroying his friendships to save his friends. Cover Art was edited out of a really cool manhua that I recomend you read if you're into reverse-isekai called The Sorcerer King.
