I don't know the exact main characters since I'm not familiar with this particular light novel. But it could have a female lead who is either a normal human or has some special ability to see ghosts, and the male lead could be the ghost with whom she falls in love.
Without having read the book, it's difficult to name the main characters precisely. But based on the title, it seems likely that there would be at least one character who is deeply involved in the mystery of the 'ghost letters'. This character might be a young person, perhaps someone who is just starting to understand the power of love. There could also be an older character, like a grandparent or an old family friend, who has some knowledge or connection to the 'ghost letters' and can provide some guidance or backstory. And of course, there would probably be a love interest for the main character, someone who they are either falling in love with or trying to re - connect with, and this relationship would be intertwined with the mystery of the 'ghost letters'.
Since I haven't read the 'love 020 light novel', I can't say for sure who the main characters are. But in a love - themed light novel, there would probably be a male and a female lead.

In the 'ghost blows out the light novel', Hu Bayi stands out as a main character. He is a veteran tomb raider with a wealth of knowledge about tombs and the supernatural.

I'm not sure as I haven't read the specific 'parasite in love light novel'.

They would be the central figures around which the story of love and parasitism unfolds.
It's likely that there are some secondary characters as well. These could be friends or family members of the main characters.

Or a family member could be the one who starts the cycle of lies for some reason related to family honor or protection.

Since the title gives only a general idea of 'love is dark', the main characters could be diverse. It might be a young couple where one of them has a secret past that brings darkness into their relationship. Or perhaps it's about an older character who has lost faith in love due to past heartbreaks and then meets someone who makes them re - evaluate their views, and they become the main focus of the story. There could also be secondary characters who play important roles in either fueling the 'dark' elements or bringing out the 'light' in the relationship.
