Sandhya, I too went through 10 pages of google search reading all crazy articles and finally figured out what Shlok meant by putting those toe rings on Aastha's feet😆.
I think its Aastha toes that are responsible for "ahaa" effect on Shlok, not the toe rings. He supposedly has a foot fetish.Its Shlok's facial hair that makes Aastha long for 'ahaa'. Nothing to do with toe rings.
