I had the same idea, like he is forced to re-live the scenario over and over again
He does! He's been stuck in the story longer than her. It was explained in one of the chapters.
Wait what chapter?
No no, he did went in before her, however he didn't lived multiple lives in the story as in repeating the story again and again. He and MC got in on the same timeline.
Sorry! The above comment is right. He hasn't been living the whole story but he has been repeating the same scene since he entered the story 4 years earlier than her. Ch 11 is where he explained it.
I'm so sorry lol he has been repeating anything at all. I misread the chapter(about the flashback panel) he just got here 4 years earlier than her. That's all.
Hasn't*
Maybe it's like this.....that our ml has lived this life multiple times and remembers it
