In "Hyde, Jekyll, and I" Hyun Bin looked at Han Ji Min and said, "I will never leave you first."

On the 8th episode of SBS Wednesday/Thursday "Hyde, Jekyll, and I" (script Kim Ji Woon, director Jo Young Gwang) broadcast on Feb. 12th, Jang Hana (played by Han Ji Min) took care of Koo Suh Jin (played by Hyun Bin). Koo Suh Jin had been ill because of extreme nervousness.

Afterwards, Koo Suh Jin freed himself of Jang Hana's touch and called her a burden. Jang Hana thought about Suh Jin in this sense and cried alone. The only person that would comfort her would be another personality, Robin (played by Hyun Bin).

Robin had a date with Hana at the chicken feet place. As he talked about the stories of his youth with Suh Jin, he comforted Hana and said, "This place specializes in chicken feet. Suh Jin is an expert in wounds and being hurt."

Afterwards, Robin came home and looked at Hana. He said, "I'm sorry I can't talk about everything. If you know everything about me and can stand it, and if you don't' throw it away, I will never leave you first." With this, he promised Hana.
