Dol-swae

A slave sold to General Gwak Seongjin's household at a cheap price. Spent his adolescent years in relative comfort despite his lowly station in life, thanks to the kindness of the ladies of the house. Learned swordsmanship from Miss Soorim and literacy from Miss So-hee from a young age, leading to a high level of martial prowess and scholarship for a slave.

Currently starting to wade deeper into romantic troubles as both Miss So-hee and Yeo-reum have begun to express their interest in him.
