Educationally aur professionally toh they both are equally capable. Dono ne Engineering kari hain, Sai ne MBA bhi kia hain. Aur acting toh dono ki lajawab hain hi. I think the difference is in their emotional capabilities. Sai seems like a total bachcha because of the way he gets excited about things and is possessive about certain things whereas Shivi comes across as a more mature person. Either they strike the perfect balance or they'll go completely off track.
This is such a wonderful way of putting it down . Thankyou for this ♥️
