Promise of an Orchid

"I'll wait for you," whispers a mysterious, red-haired woman. So goes the recurring dream Jaesin Yang has had every night since the tragic massacre at the orphanage when he was a child. When he moves to the notoriously haunted Orchid Road to delve into the meaning behind his dreams, he is nearly killed by a vengeful demon on the first night. However, he is rescued by a beautiful woman named Socheon who looks just like the woman in his dreams. Together, they join forces to help innocent demons and fight against the demonic designs of Geumgwan, the lord of all demons. (Source: Webtoon Entertainment)
