veer is clearly a side character...tbh they actually should have left his character out..I find him extremely boring ...but I suppose in order to bring out mishtys insecurities regarding marriage they had to write his character in..hopefully it will be a short lived one and they can focus more on mishty, ruhaan and pari who are the lead characters...
Why should Veer have faults for the relationship to break? He can be a nice guy . Mishti can be a nice girl , yet the relationship can break. Being nice is not the only criteria. Compatibility is the most important.
Two nice people may not be compatible physically and emotionally. That is nobody's fault.
As a viewer I have not seen the emotional bonding. If writers didn't explore deliberately or they are simply not interested is not for me to judge.
