It's that he is sensible and matured to handle things his way and many times he had given back got angry too but seeing devika his heart melts .
I too agree with jyothi that angry man are getting boring these days so Ravi is some what different I am liking it.
Even devika self talked about that Ravi doesn't give back even with her nonstop accusations and she felt guilty about it but slowly she will know infact she is lucky to get dotting hubby like Ravi
