Without reading the 'in another life novel', it's hard to determine the main characters. However, they could be characters with a strong sense of curiosity. For example, it could be a scientist who discovers a way to access other lifetimes and becomes the central figure in the story. Or it could be a young dreamer who has always felt like they belong in another time or place and sets out on a journey to find their other lives.
I don't have enough information to say who the main characters are. It could be anyone from an ordinary person trying to figure out their alternate lives to a more fantastical character like a time - traveler or a reincarnated soul.
I don't know as I haven't read it. It could be a young protagonist trying to find their place in this 'another life' situation.

The main characters are Javier and Oliver. Javier might be a character with a complex personality, perhaps he's very outgoing but also has a sensitive side. Oliver, on the other hand, could be more reserved but really intelligent. They are the central focus of the fanfic and their relationship, whether it's a friendship, a rivalry, or something more, is what drives the story forward.

It could be that there is a male lead who is on a quest of some sort. Maybe he is trying to uncover a secret related to the events of 2001 in the story. And there might be a female character who is his ally or love interest, helping him along the way.
