What's wrong if SwaSan got married in real? :\

Hello all, I'm a silent reader, not tht active here, don't watch the show regular but liking swara & sanakar's chemistry so trying. To follow it, as far I could get they wr in a fake marriage to reveal ragini's truth but now ragini make thm married but In on location vid swara was saying "what ll ma, baba, dada, dadi ll think about me? I didn't get what will n their prob? Till now they we hving prob tht this two staying as hubby wife with getting married in real now if they get married for real, what prob other might have? In fact it's good as in future no one can point on them tht they wr faking or doing anything wrong.
One more thing in a new vid saw swara without sindor & mangalsutra so I'm very confused about all this
