It was unexpectedly funny and cute i feel like i m reading onoe and kaburagi again cuz seme is very straightforward type who insults uke easily like in keeping uke touch with his reality and uke is tsundere i actually don't like tsundere they keep saying no but he keep thinking about his seme all 24 hours about his behaviour and keep challenging him so he could win as demon King but he always loses to seme who is hero , actually seme is hard to be call hero since he has personality if gangster type and evil he even out tracker in uke so he could detect just to secure him from troubles main house could bring to him and uke accepted them quite easily seme is possessive of uke but after losing many times uke finally won cuz hero fall in love with him and he has captivated him.
This manga is absolutely fun reading i find their relationship to sex scene everything perfect totally worth time I'd probably read it again.
