Some people don't know how to express what they feel but that doesn't mean that they don't feel only... i agree Maddy loves koyal selflessly but what Raj did today showed his love and care for koyal. He knew that koyal will never be ready to go to Mumbai so he instigated her to go Mumbai by insulting her by challenging her. I think this is love because raj wasn't jealous or angry on koyal instead he wanted her to utilize the opportunity given to her
