The series consists of different pairs and should be read in its entirety. However, if you don't like a certain pair, you can skip their volumes (although it's not recommended as the events in the Warui Koto Shitai universe progress in each volume). The pairs are: Mikado x Towa (Warui side), Ryuichi x Shūji (Ja Nai Kedo side), Kuon x Nanao (Mujihi na side), and Shirō x Nao (Shouwaru Ookami ga Koi o Shita Rashii). There is also a volume featuring a new pair, Makoto x Tōru (Kira Senpai to Kokonoe-kun). All pairs come together in a special volume, and a group of teens enter an unexpected drunken state. Check the recommended reading order for the series in order to fully understand the events.
