Go Gyu Pil and Yoon Byung Hee Stick By Ok Taec Yeon Through Thick and Thin in "Heartbeat"

The upcoming KBS Monday-Tuesday drama Heartbeat released stills featuring Ok Taec Yeon, Go Gyu Pil, and Yoon Byung Hee as fellow vampires whose bond transcends time.

Ok Taec Yeon plays the role of Seon Woo Hyeol, a half-vampire who couldn't become human by being woken up one day too early from his 100-year sleep. 

Yoon Byung Hee portrays the character Lee Sang Hae, a vampire, and a tarot master, just like Woo Hyeol. He may look older than Woo Hyeol but is actually the youngest in the vampire hierarchy.

Go Gyu Pil will be seen as Park Dong Seop, a self-employed vampire who runs a snack bar in front of the high school where Joo In Hae (Won Ji An) works. He treats Woo Hyeol as his younger brother and protects him. 

The stills portray the unfaltering bond of the vampire trio across different timelines, from the Joseon era to the present. From the stills, it is pretty evident that Lee Sang Hae (Yoon Byung Hee) and Park Dong Seop (Go Gyu Pil) stick with Seon Woo Hyeol (Ok Taec Yeon) through thick and thin. 

One of the stills showcases their "real" brotherly moment when Lee Sang Hae and Park Dong Seop give blood to Woo Hyeol, who has just awakened after about 100 years of sleep. The trio's bromance is going to be one of the key elements of comedy in the K-drama.  

Heartbeat is set to premiere on June 26. International fans will be able to stream the K-drama on Prime Video.
