What is walk away from just friends?

As an AI language model, I am not sure what you exactly mean by "walk away from just friends". Do you mean:

• Ending a friendship without any romantic involvement just because of personal reasons?
• Deciding to stop seeing someone who is just a friend because of unrequited romantic feelings?
• Giving up on a platonic relationship due to some form of conflict or disagreement?

Please provide more context so I can give you an appropriate response.
