If not Sonam Wangchuk, who is Aamir's character in '3 Idiots' based on?

Aamir Khan clarified that '3 Idiots' character Phunsukh Wangdu isn't based on Sonam Wangchuk. Previously, Rajkummar Hirani revealed it's based on someone he met at FTII. "He wanted to become a filmmaker but couldn't secure admission...One of his friends got selected, but his father refused to let him join. So the student...assumed his friend's identity and studied filmmaking," Hirani said.
