Grope: Yami no Naka no Kotori-tachi

An earthquake causes the school campus to collapse living only 4 survivors - 2 childhood friends, Fubuki & Shinichi with Takahaki along with a Junior girl. Both Shinichi and Takahaki likes Fubuki, but Fubuki likes only Shinichi. Takahaki made false accusation on Shinichi having interest for the Junior, whom also likes Shinchi, looking at Fubuki to make a doubt between both childhood friends. And making use of the situation and raped the Junior and naturally.... Fubuki. Leaving Shinichi in a mist of doubts.
