A girl returns to her past when she was just a child and got adopted into a family as a substitute for them who lost a daughter that looks like her due to tuberculosis or something similar. She has three brothers. At first there was hate but she decided to simply ignore her brothers because she is 'older and wiser'. She knows that the parents will die in a years time and tries to change it but they still die. However what changes is that brothers differently from last life do care for her and love her.
