Of Course, like every personal possessions have emotional value attached to it, That shoe was his most favourite one. He loves this color & he even carries it well. Not many men can carry this color.
But it's the cost of this shoe that mattered too, it costs between 120,000 to 150,000 Rs as per even his haters on YouTube. But he sacrificed it for Sana, knowing, he won't get a replacement during the show. If he had a little bad feelings for Sana, he wouldn't have done it. But then Mahira made it easier by indicating that she won't feel bad if he does it for Sana.
While the people Sana was bitching against paras was non cooperative with her on day one of her captaincy but the people she was against, Paras, Mahi, Aarti, ShefaliZ were the most cooperative. Even her closest friend Bagga was igniting fire against her, she's playing on both side. Taunting her saying "Now her own team is sleeping" to the other side.
Sana is so dumb that she even doesn't understand who's her friend and who's not. Even Shukla has given up telling her anything & may be she will have her lesson but then it might be too late to recover.
