The Our Sticky Love cast is built around Jung Hae-in and Ha Young, with Heo Sung-tae adding the threat behind the romance. Netflix’s amnesia rom-com follows a boxing coach who claims to be the boyfriend of a prosecutor who can no longer remember him.
| Actor | Character | Status |
|---|---|---|
| Jung Hae-in | Jang Tae-ha | Lead |
| Ha Young | Go Eun-sae | Lead |
| Heo Sung-tae | Baek Sang-gil | Supporting |
| Lee Jun-young | Character not disclosed | Reported cameo |
Jung Hae-in as Jang Tae-ha
Jung Hae-in plays Jang Tae-ha, a former youth boxing champion and ex-gang member who has rebuilt his life as a rural boxing coach. Tae-ha has a past with Go Eun-sae, but her memory loss erases the history that makes his actions understandable.
When Eun-sae wakes up confused, Tae-ha says he is her boyfriend and brings her into his home. His affection looks sincere, yet his insistence that their arrangement must remain secret immediately raises questions. The character has to carry both sides of the series: the softness of the romance and the danger hidden behind his lie.
Ha Young as Go Eun-sae
Ha Young plays Go Eun-sae, an ambitious prosecutor who loses her memory after an accident. She wakes in an unfamiliar rural town, surrounded by traditional taffy shops and people whose version of her life she cannot verify.
Eun-sae’s distrust of Tae-ha gives the early relationship its comic friction. She has no reason to accept his boyfriend claim, especially when his appearance and the village feel far removed from the life she expects for herself. Her investigation into Tae-ha becomes inseparable from the search for her own missing past.
Heo Sung-tae as Baek Sang-gil
Heo Sung-tae plays Baek Sang-gil, the dangerous crime syndicate leader connected to Eun-sae’s investigation and Tae-ha’s former life. Sang-gil is the pressure behind the couple’s strange cohabitation, turning Tae-ha’s deception into more than a romantic-comedy device.
His presence explains why Tae-ha believes Eun-sae must be kept close and hidden. It also keeps the series tied to a larger crime story even while the village scenes lean into warmth, awkwardness and romance.
Lee Jun-young’s reported cameo
Lee Jun-young is reported to make a cameo in Our Sticky Love. His character and the extent of the appearance have not been publicly identified, so the role should be treated as a guest appearance rather than a confirmed part of the main cast.
How the main characters connect
Tae-ha and Eun-sae are linked by a past that only one of them can remember. He presents himself as her boyfriend, she treats him as a suspicious stranger, and their forced proximity gradually changes both positions. Sang-gil connects that private relationship to the external danger surrounding Eun-sae’s lost memories.
The village’s taffy-making identity gives the title its playful image. These characters are pulled into a bond that becomes harder to separate, even as Tae-ha’s secret and Eun-sae’s missing history threaten to tear it apart.
