All I can sense that he really likes Praneet as being a friend because one cares about others' words only if one gave them importance or has positive friendly feelings about them.
Many ppl have said different things for gautam in the house, but he reacted only at footage artist of praneet as he consider him his genuine friend and didn't expected those words..
Also in 13 oct episode one can see how gautam reacted to praneet, and at the end the issue from gautam was "Praneet tum mujh se din may kitni baat karte ho" ..lol...that was like a child who is angry bcoz he is not getting enough attention from his friend.
that was cute 😳
moreover he saved Praneet out of all,not even puneet or pritam or even upen, and he said some really great things about praneet while giving the reasons to save him.
I guess Praneet also knows this somehere, thats why he understands Gautam and be good everytime at the end of any issue.
Even pritam and at times puneet stated some mean things about gautam, but praneet not even for once said anything bad about gulati.
I think more then pritam gautam, it is actually praneet & gautam 2 ppl who genuinely like each other,
