Nilavuku En Mel Ennadi Kobam: An Usual Love Story (initialised as NEEK, transl. Why is the Moon Mad at Me?) is a 2025 Indian Tamil-language coming-of-age romantic comedy film written and directed by Dhanush, who produced jointly it with Kasthuri Raja and Vijayalakshmi Kasthuri under Wunderbar Films and RK Productions. The film stars Pavish Narayan and Mathew Thomas in the lead roles, with Anikha Surendran, Priya Prakash Varrier, R. Sarathkumar, Venkatesh Menon, Rabiya Khatoon and Ramya Ranganathan.

Initially, Soundarya Rajinikanth was to direct the film, announced in 2016, with Dhanush starring, but it failed to materialise. It was reannounced in December 2023, under the tentative title DD3, as it became Dhanush's third directorial film, and the official title was announced a few days later. Principal photography commenced the same month and wrapped in November 2024. The film has music composed by G. V. Prakash Kumar, cinematography handled by Leon Britto and editing by Prasanna GK. This film dubbed into Telugu as "Jabbilamma Neeku Antha Kopama?"(transl. Oh..miss moon, are you angry that much?) based on the song in the 1997 telugu film Pelli.

Nilavuku En Mel Ennadi Kobam released worldwide on 21 February 2025 in theatres. The film received mixed reviews from critics, and became a box-office failure.
