Why the sudden change of story i mean i get it that they have same tittle but different author but I was so happy about reading the first story that the next page ruined it for me and i don't understand what's going on in the second story is it the uke who is obsessed over the seme I'm confused right now very much whatever I didn't like the second story and also both uke and seme of second story
