Nanu Prabhu is a happy-go-lucky youth who joins in a college and falls in love with Sandhya, his senior, on first sight. Despite she being older than him, he does not care about it and pursues to woo her. He is aided by his best friend Petha Perumal, a lazy glutton who drools over food, in his love quest. Sandhya dismisses his romantic pursuits and looks upon and mingles with him only as a friend. They travel in the same bus to the college and become good friends. Soon, trouble starts in the form of Sandhya's batchmates who are in love with her; they do not approve of her relationship with Prabhu. This puts them and Prabhu at loggerheads. Their clash, however proves to be an advantage for Prabhu, as it causes Sandhya to bond closer with Prabhu. After a series of events, Sandhya eventually reciprocates his love and is about to propose back to him when Prabhu is hit by a speeding van and dies on the spot. Sandhya then becomes hysterical and cries uncontrollably, with a dead Prabhu lying on her lap in front of the crowd that had just gathered at the scene of the accident. Five years later, Sandhya becomes a teacher in the same college where she and Prabhu studied, unmarried and living with the memories of Prabhu.
In early 2008, Boopathy Pandian first announced a project titled Naanum En Sandhyavum, with which he was planning to introduce his younger sibling Arjun Prabhu as an actor. He signed him for the lead male role in the film, whilst Malayalam actress Meera Nandan was approached to essay the lead female character called Sandhya, for which reportedly also Kajal Aggarwal, Bhama and Vedhika were considered. Yuvan Shankar Raja was announced as the music director for film. Following the announcement, however, there were no more news or any further details disclosed in the media and the film got shelved. In early 2010 then, reports claimed that the director had completed a film titled Naan Avalai Sandhitha Pozhudhu, starring newcomers and featuring Yuvan Shankar Raja's music. Boopathy Pandian had restarted the projects, changing its title and replacing the lead couple by two relatively unknown artists; Balaji Balakrishnan, who starred in the popular STAR Vijay television series Kana Kaanum Kaalangal and also appeared in the N. Linguswamy-produced 2009 filmPattalam, was signed as the male protagonist, whilst Meghana Raj, daughter of actors Sunderraj and Pramila, who was also earlier signed by K. Balachander for his long-delayed production venture Krishnaleelai, was roped in to enact the role of Sandhya. The title of the film was later changed again to Kaadhal Solla Vandhen as disclosed by Balaji on his Facebook site. The film's shooting was primarily carried on in and around Perambalur, with major portions being filmed at the Dhanalakshmi Srinivasan Engineering College.

Reception
Behindwoods wrote "Boopathy Pandiyan’s Kaadal Solla Vanden is not the time pass material he has produced before. It’s much less entertaining than its earlier counterparts and the fact that the storyline has very little scope for fast-paced narration leaves you stifle a yawn quite often". Rediff wrote "Now, if only the director had shown some logic and rationale in the story instead of re-working several other earlier films, this movie might have lived up to the promise it generates in the first half". The Indian Express wrote "humour in the lines, fun-filled moments, and a racy pace which keeps the audience engaged for most part".
