One thing is clear though, Shiva doesn't hate Raavi but she clearly hates him.
As much as Dhara says donon ko samajhna hai aur jhukna hai, from Shiva's last monologue this redemption is going to be one sided.
And Dhara somehow wants Raavi to come back to Pandya Niwas.
Her i hate you will disappear the moment she finds out about his sacrifice..
