Due to his belief that love is a hassle, office worker Arisawa frequently engages in one-night stands. However, after meeting university student Tomohiro and being pulled out of a bar, they share a special connection. Initially, Arisawa only considers it another casual encounter, but Tomohiro suggests they start a relationship. Though Arisawa initially refuses, Tomohiro's insistence leads to a two-month trial period. Additionally, one-shot stories "Nozomeba Eien" and "Sonna no wa Sasai na Koto" are included.
