First to some extent i agree Suicide part.
Second one, Karan should know inspite of he being a strict if his girl can choose her boy friend and make him bend to her wish, then he should think once what is happening around Ronak and Garu too. Of course this will help him understand Parth's death too.
Let's see maybe after samaira gets married, karan will focus on Raunak and Garu, or perhaps once the truth about parth comes out , karan's concern will shift towards Raunak .
