anyone know a seinen manga about an old father, who has just lost his wife due to an illness, he decided that it's meaningless to keep on living as he has lost everything important in his life so he quits his company and is about to commit suicide by hanging himself, but the phone rings at the last minute and he decides to pick it up, it turns out the police has found the bones of her daughter who ran away from home and died several years ago. He then cancels the suicide and decides instead to investigate his daughter's death, and he starts by reading her diary that his wife gave him before she died.
