No one has broken a shell, faster than Arataki Itto. But he met someone who he couldn't crack so easily. He is the eldest sibling of Sangonomiya Kokomi, his name is Sangonomiya Haruto. This man was cold, but warm when his walls are climbed over. He's rough, but gentle when the time is needed. The Sangonomiya siblings are close and always will be as close as stitches on a kimono. When a storm breaks out Arataki Itto is stuck in the middle, but Haruto comes and brings him to his home and he stays a couple of nights. Every night Arataki craves more and more of Haruto and Haruto knows completely what he's doing to him. His scent, his body, his attitude everything was driving him crazy. Until he was on the brink of breaking finally Haruto finally ends the back and forth with more teasing.
