Somebody I commented to get ready for a manipulative and trashy seme. I'm confused cause currently seme doesn't seem to be like that? Was the commenter confused who the seme was a t the beginning or there's gonna be a massive twist?? This feels like that other manhwa where the uke also was morally gray and his friend offed himself and it seems to be the seme's fault but the seme's so good at manipulation. I forgot the title lol
