The exact original recording behind va ser muy bonito is not widely documented, so it is best treated as a circulating Spanish reaction clip rather than a line tied to a single show, film or creator. Its appeal is easy to understand: the phrase is short, instantly recognisable to Spanish speakers and carries a hopeful meaning that needs little context. Online it travels mainly in short-form edits and reaction posts, where creators reuse it to frame something pleasant, romantic or long-awaited. That flexibility has kept it in use beyond any one trend.
