Should my SOP be a narrative of all the events in my life that lead me to develop my research interest? I am applying to a master's degree in computer science and while writing my SOP I see two options:


I participated in a bunch of competitions, read a bunch of papers, worked with a senior scientist and produced a draft of a paper which is about to be published. These are all chronological events. Should I describe each one of these events in a separate paragraph and explain what I have learnt from these that caused me to develop a research interest?
Should I just directly mention all the events very briefly in 5 ~ 6 sentences and the next couple of paragraphs talk about the specific topics I am interested in conducting research in, without mentioning the motivation behind what got me interested in these topics. 


While concluding I would like to mention few specific faculties whose work fascinates me. I would like to describe the works of few particular faculty members which I would like to work under(Possibly have them as my thesis advisor if it is fine by them).

Are either of these two options fine or which one should I choose preferably? Also how the should overly narrative(Tone and everything) of a SOP be?
To answer your top-level question:
Absolutely not.
Your statement of purpose should be an account of what you want to do in graduate school, and your qualifications to undertake that research. Admissions officers do not want to read about everything you've done as a researcher since you were a child. Nor do we want a blow-by-blow account of your research career.
Instead, briefly summarize your history, and move on from there. The bulk of your essay should be what you plan to do, not what you've already done.
