both are BL series with the roommates trope : ROP304 only has one couple, and it's the main, KKB will have (i think) at least one couple created thanks to the "roommates" trope so this will be their similarities
ROP304 is more related to an opposite/ennemies to lovers, with also the work place as an important think
KKB's characters are all friends but working at different places
