Brocon/siscon

Step siblings romance: the brother is a literal psychopath and the sister is a brocon who wants to stop his brother from crossing the line.

Absolutely read this if you want to laugh your ass out! The characters are a wack, it's the best!

One of the two ML is a step bro, siscon. How he supports the crazy stunts of the FL is very wholesome. He's taking on the 2nd male lead stance but the author is good in keeping us on our toes on which ending the FL will get.

ML realized he is in an otome game and his lil sister is the villainess who meets a horrible end in all routes. This siscon will do whatever it takes to protect his cute little sister.

Incest the plot is crazy be prepared.
