I wanted Ruhaan to leave Mishti's house for Veer but he wasn't that considerate towards Veer. He always kept his feelings above him. In this show I may have enjoyed Ruhaan as a character but I would never want anybody behaving like him with his friend, atleast I won't behave like him.
So for me, this is like a karma for him. I can understand Mishti she can't build her love life on her sister's tears but she should have distanced herself from him rather than sacrificing him like a non living thing.
