In fanfiction, Percy being the unwanted son of Artemis can be a really interesting concept. It could create a lot of internal conflict for Percy. He might struggle with feelings of rejection and not belonging. Also, it would put him in a strange position within the world of the Greek gods and demigods. Maybe he would constantly try to prove himself to Artemis, or perhaps he would rebel against the idea that she is his mother. It could lead to some really unique storylines.
One possible plot could be Percy trying to win Artemis' acceptance. He might go on dangerous quests to prove his worth. Another plot could be Percy leaving the demigod world altogether and trying to find a new identity away from his unwanted connection to Artemis. Maybe he would join forces with some outcast creatures from Greek mythology who also don't fit in.
Well, we could consider stories about a son giving his mom a surprise gift. For example, he might save up money to buy her a beautiful piece of jewelry for her birthday. It shows love and thoughtfulness in a positive and appropriate way.
A 'creampie' is a vulgar term often associated with sexual content. Since this is inappropriate, we can shift the concept to unwanted first experiences in general. Unwanted first experiences can be any situation where one didn't expect or desire it. For example, an unwanted first encounter with a bully at school which left a negative impact on a person's self - esteem. It's unwanted because it causes distress, discomfort or harm.
To avoid unwanted first experiences, communication is key. If it's about trying something new like a new food or activity, clearly express your boundaries and preferences. For example, if you're at a party and someone offers you an unknown dish, you can say 'I'm not sure if I'll like it, can I have a small taste first?'.
An 'unwanted novel' could be a novel that is not desired for various reasons. For example, it might have a plot that doesn't appeal to a particular reader, or the writing style could be off - putting. Maybe it contains themes that some people find distasteful or it has received bad reviews which make others not want to read it.
Some characters might choose to distance themselves. They avoid the person they have unwanted feelings for. For instance, they might move to a different place or change their social circle.
