Sachein is a 2005 Indian Tamil-language romantic comedy film directed by John, and produced by Kalaipuli S. Thanu.

[5] Sachein, a carefree and happy-going guy, joins a college in Ooty and falls for Shalini immediately on seeing her in first sight.

Shalini studies in the same college as Sachein and is considered a popular and beautiful student, while also being a short-tempered and arrogant girl with an upper-middle class status.

Sachein learns all of this information about her from Arnold aka Ayyasamy, a man who has studied in the college for about nine years and keeps studying there because he thinks that students should give their respect to their college professors, while also informing Sachein that there are so many boys trying to impress her.

Santhanam, who is another student in the college, also loves Shalini, but he feels jealous seeing her and Sachein being good friends and decides to separate them.

To her surprise, Sachein informs that, although he has not written it, the content present on the wall is true, which means that he is in love with Shalini.

The film was released on 14 April 2005, coinciding with Tamil New Year, also clashing with the Rajinikanth-starrer Chandramukhi and Kamal Haasan-starrer Mumbai Xpress.
