Sawaranu Futari wa Nani wo Suru

"I swear I'll never touch you again." "So won't you try... something more exciting than sex with me?" Otaku office worker Touko Amemiya has fallen in love with her section chief Shuuichirou Hasu. After getting some help from a supporter from the sidelines, the two end up together and she confesses—only to get shot down. But Amemiya, realizing Hasu had lied to her, chases after him but suddenly his breathing becomes rapid and he collapses! They can't touch each other, but that won't stop them. A pure, platonic... and sexual romance starts now.
