Manga XXX - grope yami no naka no kotoritachi 2

Two childhood friends, Fubuki and Shinichi, together with Takahaki and a junior girl, are the sole survivors when an earthquake destroys the school grounds. Shinichi and Takahaki both like Fubuki, although Shinichi is the only one who enjoys Fubuki's presence. For the purpose of sowing discord between the two boyhood friends, Takahaki falsely accused Shinichi of having feelings for the junior, who is also a fan of Shinichi. As a result of the scenario, the junior was raped, and, of course, Fubuki was there. Shinichi is left in a fog of uncertainty as a result.
