For six long years, they kept their relationship under wraps. In an industry where link-ups are often publicity stunts, Jyothika and Suriya were notoriously private. During the shooting of Perazhagan (2004), where Suriya played a double role (a hunchback and a lover boy), the chemistry was so palpable that the media went wild. They never confirmed anything, but they never really denied it either. It was an open secret whispered in Kollywood corridors.

The year was 1999. Suriya was a newcomer struggling with Nerukku Ner. Jyothika was a rising star. They were cast opposite each other in Poovellam Kettuppar. The film was about a couple who fall in love despite family opposition. Art imitated life almost immediately.

The Jyothika-Ajith pair was box-office gold. Films like Vaali (1999), Kandukondain Kandukondain (2000), Citizen (2001), Villain (2002), and Rajavin Paarvaiyile showcased a range of relationships. In Vaali, she played a woman caught between a good brother and an obsessive, psychotic one—a storyline that was dark, twisted, yet romantic. The song "April Maadathil" remains a testament to their effortless chemistry. They weren't just lovers on screen; they were equals, often fighting or teasing, which made their romance feel real.
