Help me with my story QAQ

Yeah the story premise im gonna need a bit more to go in depth with. Im waiting until i get off of work so i can put everything here. I have a love interest and potential main characters to throw in

i feel like if it's going to be a pretty edgy story, maybe you could make the new wife sort of infatuated with the boy since she has no attention from the father? there could be some parts where she tries to do insane things to get him to pay attention to her or something. maybe make her slightly more crazy as the story continues, and then have a pretty big scene where she lashes out or something. just an idea!! :D

Well the wife is a jealous woman, the reason the dad neglects them is because as the boy got older he started to look more and more like the mother. The wife is actually his mistress from when the mom was alive. So she uses the boy as sort of payback to both of them the husband for not paying attention and the mom for having his heart still longing for her. It isnt a main plot point and i dont wanna dive too deep into her life cuz he ends up killing her

Yeah but i like where you are trying to go with it. I sorta made that mistress part on the spot cuz you said that XD she is an evil woman who takes advantage of the boy and the death of his friend makes him snap.

Im sorts pulling inspiration from other stories. Like a manga called doll's code is wher ei got the idea for a stepmother thing. Only they used a real mother sleeping with son cuz he looks like dad that left her and she tries to kill the son cuz he thinks its wrong for her to do that.

(I suck at writing so let me be... ) god damn it I fukked up already? XDDD sorry my idea is isekai and another world-ish but I will break some 4th walls OwO ch1 story starts like every normal fantasy one you have the sword male character let's call him hero. the female character who backs him up priest class let's call her heroine. you saw em training as kids in their village as kids... monsters overrun the place yes we need a heavy back storry... they are the sole survivor of the village... they get picked up by some royal and got adopted in their household starting the real training phase... they start to go out on small adventures and starts to form a real party with a magician and a tank... now the party is complete. ch2 Now we turn our perspective solely on the bad guy za demon king/skeleton king he is the one controlling all the monster in the world and get em to attack viallges you can see him giving an order to attack a small village... yes this is a backflash to him ordering to kill their whole village... it was an easy plan multiple goblins on to the village. ofc they won and the king was very pleased. tho he had a bad feeling about this... always looking like he is searching for sth in the room... ch3 now this is were the fun begins he found out the hero party was still alive so he makes prep to go and finish em... we a not in a shounen manga here so he gets all his troup to go face em all at once---- battle begins... some generals of the king told him he could handle em alone so he gave him the free hand on this matter... obv by the power of fukking friendship he got killed by hero party... the king was furious ch4 demon king now enraged told em all to attack em at once.... well this is were the hero party got overwhelmed and massacred... yep they died hah! Now the camera turns back to the now satified demon king as he inspect the heros remain... he noticed something odd but didn't care for it and moved on with his army... heros remains kinda disintegrated... ch5 a new hero is born... yet again the demon king realises it and now send the whole group to kill the whole viallge... now flashbacks to see that he only does this to villages that seems like a hero is born in... he realises a pattern, for some reason he can't kill of the hero party no matter how much he tries they get reborn somewhere. now he realises sth... *looks at the viever* (jap this is the 4th wall breaker) he realises all his action was somehow realated to the heros party... he now starts to plan to break out of this cycle... maybe thru a portal in another world I kinda stop here cause I still don't know what to do with this xD chx demon king kills you the mangaka in the real world with it ending the endless cycle of switching worlds and the never ending hero reborn stuff OWO wow dat's way too much shit OwO
