The song Kichu kotha from the soundtrack of Aari is a melodious duet that portrays the blossoming of a romantic relationship between Yash Daasguptaa and Nussrat Jahan, who play a couple in the film. Sung by Muhammad Irfan and Anwesshaa, Kichu kotha expresses the pure and innocent emotions of young love, bringing alive the vibes of romantic songs of yesteryears. The song depicts the characters of Yash and Nussrat, who are mere acquaintances, meeting by chance at a street corner and striking up a conversation, which later develops into a friendship. Their subtle chemistry is evident from the outset and as the song progresses, their friendship evolves into a beautiful romance.

The video of the song is full of picturesque scenes where he is seen showing her around various sightseeing spots. The song is beautifully shot, capturing narrow alleys and old-fashioned architecture, quaint gift shops and cafes, and breathtaking glimpses of a rocky sea coast replete with a fort and a vast promenade. In the song, she is more confident and assertive. It is she who also encourages him to drop his shyness and take her out on a date. While Nussrat looks cool, calm and fits effortlessly into her role, Yash also slips neatly into his character of a diffident young man, unsure of himself and ecstatic to discover her reciprocating his feelings. The ending of the song, where she puts a seal to their relationship by slipping a bracelet made of beads around his wrist, is heart-touching for its beauty and simplicity and will resonate with lovers of all ages, taking them back in time to remember their own first mementoes of love.
