Tsumaranai Ninomiya-san
Boring Ninomiya·つまらない二宮さん
Ninomiya works as a teacher at a preparatory school and has a pattern of his relationships ending due to his perceived lack of excitement. After a breakup, he meets Sada, an attractive and charismatic man, and they spend a night together, expecting nothing more. However, the story explores the dynamic between Sada and Ninomiya, as well as other contrasting pairs like the serious Takama and the energetic Senba. The narrative centers on handsome men and their less conventionally attractive romantic interests in the series.
