Oasobi wa Sokomade

Two editors, Kudo and Hisakawa, find themselves in charge of the best seller Tarou and even run into each other at the famous writer's house on business. By the time their three-way meeting comes to an end, the seasonal typhoon makes landfall, obstructing the two editors' train rides home. Reluctantly, Kudo agrees to stay the night at a hotel with Hisakawa. Hisakawa, seeing that Kudou can't sleep, calms him down next to him in bed. One thing leads to another, and the two go as far - and deep - as two people can go.
