> When talking about someone else, does always mean that you have feelings for them?
No, it depends on the context. can be a perfectly safe choice in many cases. For example, if someone asked a question like "?", one can easily tell it's not about romance but about politics.
But of course there are also situations where you need to avoid misunderstanding. The easiest option is to choose objective expressions that do not directly describe your feelings (e.g., , , , , , ). It's also common to use and explicitly tell the type of your liking, e.g., , , , . is particularly handy.
