I need some drama

Don't settle for that cheap imitation. You get the real forbidden love with the GOAT Not Equal. Real incest biological father and son forbidden love time travel yummidelicious goodness https://www.mangago.me/read-manga/not_equal/

More general forbidden love incest, mostly brother x brother. These are my personal favorites, guarantee the plot is there, not just slop

Twins. Inferiority complex, yearning, chaos.
