hear me out: isekai where the MC gets transmigrated into the protagonist of an eroge he played. as the protagonist, all the main heroines are heavily inclined towards him and can all easily become harem members if he wished it. however, the MC's waifu can only be reached in the final arc if he doesn't romance anyone else before then. in the real world, he unlocked her ending exclusively over a dozen times, had multiple figurines of her (some of which were duplicates for the sake of preservation), and even though this is a part of his black history: wrote a 200-page fanfic of her. he couldn't even fap to the other girls despite it being an eroge because he was so damn loyal to her. now in the isekai, the main heroines have started to gravitate towards him and he's looking for ways to reject them but there's one problem: the bad end. in the original eroge, the protagonist gets a GAME OVER if even ONE (1) of the main heroines hate him. he doesn't know what a game over means in the isekai and isn't willing to find out. thankfully, he has a dating sim cheat ability: he can see all of the "correct" and "incorrect" dialogue choices, can see detailed stat pages of all the girls (that reveal things like affection levels, likes, dislikes, and other personal info), and even gets a notification of upcoming events relevant to romantic progression. it's a story where the MC has to dance between hate and love, both of which spell a bad end for him. pic not related.
