After Ryou's father remarries, he's not sure what to do with three new brothers and a stepmother at the age of 19. As he comes to appreciate his happy new home and family the glue holding them together starts to come undone. How will these four brothers weather tragedy after tragedy and stay together? (Note: Ryou's name was previously mistranslated as "Ame" in the first few chapters by scanlating group STK Translations)
