The first world will be 'The Way to Protect Female Lead's Older Brother'.
It will have an OC Main character.
The love interest is Roxana Agriche.
This will be a Yandere X Yandere thing. Both will become madly in love with each other and will be obsessed.
Note - MC is possessive, powerful, cruel, psycho in the head as well as sadistic.
Roxana will also gradually attain all traits of a Yandere.
They will be like 9/10 as a Yandere which means that they can kill anyone for their significant other. Like - If a butler gave a flower to Roxana, MC will not say anything in front of her but cruelly torture that man behind the scenes.
This world may include - Torture, Murder, Manipulation, Suicidal Tendencies and Psychopaths.
If you are not okay with the topics above, then you are free to leave the book.
I am a newbie in writing yanderes and Parmesan has assisted me a lot.
Check out his novel 'I started to gain sentience in an eroge' if you like Yandere harems.
