Maybe but I dont think he'll melt anytime soon. He shouldnt either. Dev is proudy and egoistic like Darcy from Pride & Prejudice. He is going to try his best to deny any feelings for Kaajjal, first to himself and then to others. Plus, it seems like Dev doesn't want to fall in love. This is a guess but falling in love would make him weaker and less coldhearted, which he doesnt want to be. His goal is to always be evil or something. 😕 😆 Dev doesn't wants to give into his feelings, whatever they may be at the moment. If he melts now, what will happen next? The show will get kind of boring.
