The two main dudes worked in an office together and ABSOLUTELY DESPISED one another (since highschool i believe). The main guy was kinda short with light brown hair and the other one was tall with black/blue(?) hair. The black haired guy found some sort of supernatural doll(?) that would do something sexual the the shorter guy. I also remember a scene where the shorter guy's girlfriend breaks up with him because she finds a dildo. I also think bondage was involved??? I also think the word 'hate' was in the title. I haven't been able to find this manga/manhwa in AGEA so if anyone could find it for me i would be SO THANKFUL!!
