Onir-Purvi!

Why will a man of sane mind marry a girl who he barely knows for days but is carrying another man's child. He is a GYN so he obviously understands everything. May be he is Gay, and this is a sham wedding? As such, the sensitivity he portrays, is not possible without a romantic interest... I mean, how!??? With all respect to gay people, I am not saying this in a bad light. I just dont know how Ekta will remove him from the equation!
