Achievement tale.
Victory narrative. This phrase can be used in place of success story. When we think of a success story, we are thinking of a sequence of events that led to a person or a group achieving something great, which is exactly what a victory narrative implies. It gives the sense of a story being told about a victorious journey, whether it's in business, sports, or any other area of life.
Business achievement chronicle.
A single phrase can start a great story by creating mystery. For example, 'The door was ajar, and a strange light seeped through.' This makes the reader or listener want to know what's behind the door and what the light is.
Life account. A life account can also be used to refer to a person's life story. It gives a description of the events, experiences, and development throughout one's life.
A story of love can also be called a love narrative. It emphasizes the aspect of it being a narrative that revolves around love. For example, many classic novels are love narratives where the plot is centered on the relationship between two characters in love.
No, it's not a common phrase in general English usage. Most people would just say 'end of story' without the '30' in front. The '30' seems to be something specific to a particular situation or group.
I don't think it's common. Bedtime stories are generally associated with positive things like comfort and relaxation. Saying 'no no no' to them goes against the normal perception. However, in some specific situations like when a person is very tired and just wants to go to sleep without the distraction of a story, it might be used.
