I'm not sure specifically as I haven't read this particular fanfiction. But it might be about the characters from the 'Percy Jackson' series (the seven) discovering that Nico has self - harming behavior. It could explore their reactions, how they deal with it, and Nico's journey towards getting help or dealing with his inner turmoil.
One common theme might be the struggle with mental health. Nico's self - harm is a clear indication of some internal distress. Another could be friendship and support, as the seven will likely respond in some way to help him.
I don't think it's a very common or popular theme. The Percy Jackson fandom usually focuses more on positive relationships and adventures among the characters. Choking is a rather dark and extreme concept that doesn't really fit the general tone of the fandom most of the time.
One possible plot development could be Nico seeking justice for Percy. He might start to investigate the abuse on his own and gather evidence against the abuser.
I'm not sure where you can specifically find a fanfiction with that exact plot. You could try popular fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. Just search for relevant tags like 'Percy', 'Nico', and 'Will' to see if such a story exists.
One possible fanfiction could be 'The Unseen Pain'. In this story, Percy might be crying due to the overwhelming pressure of his demigod duties. Nico stumbles upon him in a secluded corner of Camp Half - Blood. Nico, initially hesitant, decides to approach Percy and offer his silent support.
One common plot twist is that Percy actually realizes he has feelings for Nico too, but he's been suppressing them. It's like a sudden realization that hits him when he finds out Nico likes him.
Nico might be initially shocked. He could feel a deep sense of anger towards whoever was responsible for Percy's abuse. Then he would probably become very protective of Percy, vowing to keep him safe from any further harm.
Well, in some versions, Percy might be initially shocked. He could be like 'Whoa, I had no idea!'. Then he might start to see Nico in a new light, with more understanding and compassion.
The 'cut out girl novel' could potentially revolve around a young girl who is excluded or made to feel like an outcast. It might explore themes such as loneliness, identity, and the search for acceptance. Maybe she has to face challenges that are unique to her situation of being 'cut out', like having to build new relationships or discover her own strength in a difficult environment.
They would likely be shocked and extremely worried. They might immediately try to stop Percy from doing it again and get him some help, like finding a healer or someone who can offer mental support.
