Because they dead ass cut out a whole arc specifically we were supposed to be in baños for months and there was a whole family arc there before he goes back to Andante. I wanna say they cut like 40-ish novel chapters maybe more
He lives in Argentina for a long time. Gets to know a local family, the daughter 'falls in love' with him (she's a child it's her first crush) the son is a smart kid who is going to be a Esper in future. The boy is the only Esper in the village and his ability hasn't manifested yet. When it does he gets recruited by 2nd MLs guild and MC gets the boy to promise not to mention him when he goes. Then the mutated gates start to open in Argentina and the village and some other areas get evacuated. When he's on his way to be evacuated he hears all that stuff about ML and that he's going into one of the gates. He goes there and sees him collapse and is caught by 2nd ML who makes the same offer as he did at the end of the most recent chapter. I think in the novel this section covers about a year. These are just the highlights. They also left out quite a bit about what happened while MC was at that other guild and he and the other guide actually get to be friends that's why he risks himself being hurt to yell out to MC to run away and hide like he's dead. The section where he runs away the first time is also longer in the novel though not a lot happens in that bit, but way more time passes then shown here, like months where this makes it look like days.
Damn... Feels like a whole season just got axed!
Novel readers tell me why the chasing arc ain’t that long?? (picture that one stan twt gif of a judge facing forward confused)
