Most likely not. Abuse in any form is an unethical and often disturbing concept. In fanfiction, it can distort the original intention of the source material and create an uncomfortable reading experience for those who come across it.
I'm not entirely sure as 'abuse' in fanfiction is a concerning topic. It could potentially be a fan - created story that involves some form of mistreatment in the context of the 'boku no dake' (which might refer to a particular series or character). However, such content often goes against positive and healthy storytelling.
One possible plot could be the protagonist's friends trying to rescue them. Maybe they follow a series of clues left behind by the kidnapper. Another could be the kidnapped person finding a way to communicate with the outside world using some unique method. For example, they might use Morse code through tapping on the walls if they are locked in a room.
Yes, it is. It has an interesting concept where the protagonist can level up just by eating. The story often combines elements of adventure and the unique leveling system in an engaging way.
Well, 'taberu dake de level up novel' sounds like an interesting concept. It could be a story where the act of eating is not just for sustenance but is the key to progress in a game - like world or a fictional realm. The novel might detail the character's journey as they figure out which foods are the most beneficial for leveling up. There could be a whole system of food rarity, taste, and quantity all affecting the leveling up process. For example, a small amount of a very rare food might level the character up more than a large amount of common food. And there may be challenges like finding enough of the right foods or dealing with rivals who also want to use eating to level up.
Hard to say. It could be on hiatus, but without concrete information, it's difficult to give a definite answer. Try following the mangaka's social media or the manga's official website for the latest.
