Fairy Tail: Marry the Dragon Slayer Queen Erin at the beginning

Description

Ian traveled through time, but he didn't panic at all...
Because there's no point in panicking, who allowed him to travel to the MAX dangerous Fairy Tail world? !
Let me ask you, in a world of magic, how can it be that the final BOSS is immune?
It’s better to leave this problem to the protagonist to solve...
In his entire life, Ian just wants to eat and die in the Fairy Tail guild.
Until X778, a small crimson glutinous rice dumpling came to the door.
Ian has since turned on the dream simulation function.
Ever since, Ian has crossed countless timelines to save tragedy.
In Ian's dream, he traveled four hundred years ago and killed the general who had trashed Irene.
Saved the Gray family and Uru, and killed Deliora in seconds.
Help Olgaste and Mavis get to know each other, and let Olgaste go to the Western Continent to work as an undercover agent...
Just when Ian always thought this was a dream.
Erin: "Yes, Erza is your daughter."
Ian: "Huh?!"
Selene: "Ian, you have to admit what you did."
Ian: "What are you admitting? It was all in a dream. Can't I be more unrestrained in my own dreams?"
