Do gta online missions involve gta v characters?

The only verified information available states that Grand Theft Auto V follows three protagonists – Michael De Santa, Franklin Clinton, and Trevor Philips – in a single-player campaign. There is no mention in the evidence of the multiplayer component, GTA Online, or any interaction between its missions and the characters of the single-player story. Therefore, based solely on the supplied source, we cannot assert that GTA Online missions involve the GTA V protagonists. Any claim about such interactions would require additional evidence not present in the current data set.
