Yeonwoo is Lee Geon's friend, someone who is pretty close with Geon and she's actually the ophi God, the one who gave Geon the power. She was targeted and before she died she give her throne to Geon. Also in backstory chapter, it's shown Geon to have a feeling for her. Somepeople said Geon loved her like a family, but for me it's clearly Geon have a romantic feeling for her before tho don't know what will happen in the future. ╮(￣▽￣)╭
