i dunno why people say that raj and naina are serious people. according to dj the serial is portraying the present day characters of raj and naina. both of them had a happy past - before the death of naveen. naveen had an important role to play in both their lives. his death was a major loss to naina and a big shock for raj who witnessed his brave batchmate commit suicide. raj was totally helpless and guilty for not being able to save him and so his life after naveen's death was not so happy as before. naina lost a friend guide and philosopher when her brother died and she too was left sad, helpless and frustrated. naveen's death changed naina's and raj's life and it is apparent that both have forgotten to laugh and be happy. but it is fate that rn have come together. they seem to share the grief and pain of naveen's death when they r with each other. but at the same time they enjoy each other's company and have spent happy moments with each other as shown in the mentorship program.
naveen's qualities are distributed in both raj and naina. raj is sensible, mature and a perfectionist in every matter like naveen. but naina is courageous , determined, truthful and has a clear conscience like naveen. rn r meant to be together and eventually it is raj who is going to instil naveen's other qualities in naina to make her the best cadet in kma!
if they unite they will perhaps be one of the most happiest couples in this world!
