Usotsuki Paradox

The story is about an office worker named Hinako Seiyuu and a co-worker named Shunsuke Yokado who’s in love with her. In order to deal with the loneliness of being in a long-distance relationship with her real boyfriend, Hinako agrees to start seeing Yokado on the condition that they won’t have sex. However, as Hinako begins using Yokado as a substitute lover, the nature of their unconventional relationship becomes increasingly ambiguous.
