A dark romance holds the secret to a serial killer’s past in Netflix’s upcoming Taiwanese drama Had I Not Seen the Sun. Coming to Netflix in Q4 2025, Had I Not Seen the Sun stars Chiang Chi, Tseng Jing Hua, and Moon Lee. Here’s what we know so far. 

Had I Not Seen the Sun is an upcoming Taiwanese drama written and directed by Chien Chi Feng, who previously wrote dramas such as Someday or One Day, Rainless Love in a Godless Land, Marry Me, Or Not.

What is the plot of Had I Not Seen the Sun?

Netflix has provided a detailed synopsis for Had I Not Seen the Sun:

“Zhou Pin-yu (Chiang Chi) visits a prison to interview a serial killer Li Ren-yao (Tseng Jing-hua) for a documentary. Although it’s their first meeting, Pin-yu discovers that Ren-yao not only doesn’t resemble a criminal who killed ten people, but also exudes a strange sense of familiarity through his innocent gaze. What surprises Pin-yu even more is that she dreams of Ren-yao that very night — and in the dream, the two are as intimate as lovers?! Pin-yu also encounters a “female ghost” (Moon Lee) dressed in a high school uniform and is frequently dragged into terrifying nightmares, even becoming possessed by the ghost. Upon investigating, Pin-yu learns that the ghost, named Chiang Hsiao-tung, has a hidden past with Ren-yao. The ghost’s bizarre actions while possessing Pin-yu all seem to point toward meeting one specific person…”
