There was no real-life romantic relationship that developed between the lead actors of Operation Proposal, including Yoo Seung Ho and Park Eun Bin.

Although their on-screen chemistry as Kang Baek Ho and Ham Yi Seul was praised by viewers and helped drive the emotional depth of the drama, both actors have maintained a professional friendship off-screen. Neither Yoo Seung Ho nor Park Eun Bin has confirmed any romantic involvement with each other during or after filming.

Their close and natural performances were a result of strong acting skills and possibly a comfortable working rapport, but not a confirmed real-life romance.
