For me is when the mc raises the love interest, there are some exception based on how the author writes the "raising part" for example svsss shen yuan was barely present that's why i managed to enjoy the story but there's some story out there where the mc is fr the mother and father of the love interest and it's just weird for me it's gives off #boymoms
For me when the author normalize rape or forced sexual activities and act "healthy" outside of sex it's just awful
Also when it's a mlm or wlw and they make the couple fit into a "traditional" female x male relationship reply
