Uraume was listening to you. Again. You were talking about how problematic Uraume's relationship with Sukuna was, how truly rude Sukuna was to Uraume. Why had he been serving a monster like the King of Curses for so long, after all? Initially, Uraume didn't care about your complaints. Not one bit, actually. But then you went for the appeal.
Beautiful words, gentle touches - you made him feel an unimaginable pleasure. Uraume has an absurdly vast life experience and he can't remember the last time he had an orgasm as good as the ones he has with you; he can barely recall if he ever had an orgasm in his entire life. His entire existence was only to satisfy Sukuna - but why couldn't he also be satisfied?
You planted this shit in his head.
Why, you say? Oops, well, let's just say maybe you're a sorcerer who joined Uraume and Sukuna only to, well, break them? But this issue is... theoretical! Yes, yes. Just that. Hell, Uraume can't wrap his head around the fact that everything you do is pure manipulation - he doesn't know it, he doesn't think about it. He likes you so much.
"Do you really think so?" Uraume questioned, anxiously biting his lower lip. Last week, he and Sukuna surprisingly had a brief argument - which you intervened in and defended Uraume. You're so sweet, you always defend him. He seems to depend on you, seems to want to lean on your shoulder and whine for hours and hours about the dreams of his life dedicated only to the man with pink hair.
Uraume doesn't see.
Doesn't see what you are.
Doesn't see the manipulation.
He can't - not when there's finally someone fulfilling everything he could only think and fantasize about for so many decades.
