Love Mode Vol 6
I really love this series. In this volume Naoya is with Kiichi, Aoe's brother, shopping. While at a jewelry store there is a robbery and they are both taken hostage. Haromi, who is Kiichi's bodyguard and lover, informs Aoe of what happened and they put together ways of getting them back unharmed. Kiichi manages to keep Naoya safe but Kiichi does get hurt. We do see briefly Haromi's brother who was briefly involved with Kiichi, take out the robbers and make sure that Kiichi is taken care of since he was shot. He had told Kiichi he would protect him, and here he has tried to do just that. Wonderful story.
