If you loved Zhang Linghe in Pursuit of Jade, his new drama is here: Overdo (这一秒过火), a 1920s Republican-era Shanghai romance that started airing on July 19, 2026. Here's the cast, the premise, and where to watch it.
Quick facts
- English title: Overdo
- Chinese title: 这一秒过火 (Zhè yī miǎo guò huǒ)
- Episodes: 33
- Premiered: July 19, 2026
- Genre: Republican-era (民国) romance / melodrama

The cast
- Zhang Linghe (张凌赫) as Murong Qingyi — the male lead. Zhang Linghe is fresh off leading Pursuit of Jade, one of 2026's biggest C-drama hits, so Overdo is the drama his fans have been waiting for.
- Wang Churan (王楚然) as Ren Susu — the female lead.
- Fu Xinbo (付辛博) in a key supporting role.
The plot (no spoilers)
Overdo is set in the glamorous, dangerous world of 1920s Shanghai. Murong Qingyi, secretly switched at birth, spends years enduring abuse from his adoptive father. Fleeing as a teenager, he's rescued by Ren Susu — but the rescue brings catastrophe down on her family.
Years later, the two cross paths again and slowly fall in love. Then, to protect the people around her, Ren Susu fakes her own death and disappears. Three years on, she returns — engaged to become Murong Qingyi's sister-in-law. It's a classic love-hate, fate-and-sacrifice melodrama built on the intense chemistry between the leads.
Where to watch with English subtitles
Because Overdo is carried on Viki and WeTV, it's easy for international viewers to follow along with English subtitles (Viki requires a Viki Pass; WeTV and iQIYI have free and paid tiers).
