They've been showing Kairav as the over protective brother for Akshara specifically. With Arohi, it seems likely a formality because I noticed he didnt mind Arohi with Abhi in the trip but if Abhi was anywhere near Akshara then he started to give those detective glares. So thats just the writers wanting Abhira to have hurdles like Kairav.
I can already see him getting fond of Abhi and respect him too but that will all be at the end when all this mess is cleared.
I just didnt like Kairav in the previous episodes because it felt more like he was confirming his doubts on Abhi rather than defend his sisters. He knows Akshara has feelings for Abhi yet he never mentioned this or even thought about it. He also knows Arohi can be difficult so he was the best person there who could have put two and two together.
