[JoJo's Bizarre Adventure] Is It Wrong to Put a Shoujo Manga Setup in a Shonen Manga?

Known facts: Only people with Guardian Characters can see other people's Guardian Characters. Only people with Stands can see other people's Stands. Guardian Characters reflect a person's inner desires and are the manifestation of their spirit. Stands also reflect a person's inner self. Conclusion: Guardian Character = Stand Amami Haruki calmly tore up the piece of paper with the equation on it. What the hell!!!! Is it really okay to put a shoujo manga premise in a shonen manga!!!! This was supposed to be a Jo4 story, but I ended up starting plots for Jo3 and Jo5 too! (...) I have no idea how I ended up starting this story. You can tell at a glance this is going to be absurd. I need to think about how to make it absurd. Theme: Love and justice
