Eun-mi
Eun-mi is Harvey Harvington's wife in BLOODMONEY: Requiem, and she is reachable only through one specific choice in the Requiem campaign.
How to Reach Her
Eun-mi appears only if, at the moment Harvey catches the Scissors mid-air and asks who you really are, you choose to answer him instead of staying silent. That conversation slowly builds toward a phone call with Eun-mi rather than the confrontation that follows the silent branch. See the Requiem Campaign Guide for the full branch, and Harvey's own page for how his character connects to hers.
Why Players Look for Her
Because she's locked behind a specific dialogue choice rather than a purchase or an ending, Eun-mi is the part of BLOODMONEY: Requiem most often missed on a first playthrough — most players discover the Scissors moment, panic-click through it, and never see the phone call at all. Deliberately choosing to engage with Harvey's question instead of clicking past it is the only way to change that.
Beyond her role in that one scene, the game does not give players much more to go on about who Eun-mi is outside of the call itself — which is part of why the Requiem branch that leads to her is considered one of the more meaningful moments to seek out on purpose.
