After I Transmigrated into a Book, I Vowed to Make the Male Lead Fall for a Man

The Mortal Path to Immortality is a somewhat unusual harem novel. The male lead is a half-demon, half-human who follows a dark path. There is really only one thing that makes it unusual: though he has plenty of fangirls, he never sleeps with anyone, not even by the end of the story! So Jiang Yutian, a fujoshi, takes matters into her own hands, drawing all kinds of doujinshi and writing fanfiction. But the male lead is such a top that she feels awkward putting him on the bottom... And then one day, she transmigrates into the story as the male lead's senior sister... Jiang Yutian: At last, I can fulfill my wish! Song Jie: Senior Sister has been looking at weird stuff again... A few warnings: 1. It may be brainless or chaotic, so please go easy on me. 2. There's a cheat called Arknights. 3. I'm lazy, so updates will be slow... 4. I'll add more if I think of anything...
