When a love story is told through voices rather than glances, it often carries a deeper intimacy. That is the emotional pitch of Kaadhal Kathai Sollava, whose trailer dropped on Monday and immediately set the tone for a film that places human connection at its core. Fronted by Vijay Sethupathi, Jayaram and Nakkhul, the romantic drama unfolds as a series of confessions, each shaped by longing, regret and hope.The trailer opens in a radio station, where Vijay Sethupathi appears as himself, stepping into the role of a guest host for a segment titled 'Kaadhal Kathai Sollava'.
