I think i kinda understood what mangaka wants to tell from behaviour of seme , he was normal guy not confident before he hates uke since he look down on him , found glasses from demon which made him sadistic af he raped uke and humiliated him and took him down on his knees , them he realised he had done bad to uke cuz he is terrified of him then seme decides to return these glasses to demon but he didn't take it cuz he told him it's your true nature glasses have took out ur true nature , still years later seme met uke since uke approached which is typical since he wanted to be with seme despite he raped him , now still seme feel empty cuz uke obey him which side he likes of uke is arrogant and resisting type , still seme changed and uke changed what change is that seme no longer desire anything he wanted to humiliate uke but now it's not that anymore he is quite unsympathetic guy i guess but still it's good read cuz his behaviour is very much of my liking well raping someone is not good since its fantasy i will overlook it. I listened its op "under the DARKNESS" i kinda loved that song so much.

It's so cute this mangaka's art is good as well i love how starting two different couples are sadist like first story one was sadistic seme then 2nd one with sadist uke and last one was quite forgetful but i probably enjoyed starting ones to make your love one fall in love foold and tease them first then tell the real you i like it even though it's cliche but it's good read.
