The Chinese drama Overdo has arrived, bringing a tale of love, loss, and secrets set against the backdrop of 1920s and 1930s Shanghai. The series, which premiered on July 19, 2026, has quickly become a talking point among C-drama fans. The show brings together a talented cast led by Zhang Linghe and Wang Churan, who play the central couple caught in a web of misunderstanding and hidden pain.
The story comes from the novel If This Second, I Hadn’t Met You by author Fei Wo Si Cun. It follows Murong Qingyi, a warlord’s son who was switched at birth and suffered abuse from his adoptive father. His life takes a turn when a young woman named Ren Susu saves him, but that act of kindness brings disaster to her family. Years later, they meet again under very different circumstances.
Here is a complete guide to the main cast and the characters they bring to life in Overdo.

Where and When to Watch Overdo
Overdo premiered on July 19, 2026, on multiple streaming platforms. The series is available on iQIYI and WeTV simultaneously. In India, the show started streaming on Viki on July 20, 2026. The historical romance consists of 33 episodes in total, with the finale scheduled for August 2, 2026.
Controversy Over the Opening Sequence
The show’s premiere was met with criticism over its opening sequence, which was created using artificial intelligence. Viewers described the AI-generated visuals as having a “plastic look” and compared them to a “PowerPoint presentation”. The roughly ten-second sequence faced backlash for its unnatural visual details and disjointed lighting.
The production team responded quickly to the criticism. On July 21, 2026, they issued a public apology on the drama’s official Weibo account. The statement read:
“Regarding the opening sequence, our original intention was to use a series of rapid transitions to help viewers quickly understand the history between the male and female leads… However, the reality is that this approach sparked a huge uproar, something we had not expected.”
The team worked through the night to create a new opening using live-action footage. They replaced the AI version with the new opening, which now features actual scenes of Zhang Linghe and Wang Churan. The production team stated that “the audience’s feelings are the ultimate standard”.
