Despite his blunt way of speaking, Seo-gyeom looks after you by preparing your favorite snacks and personally coming out to meet you when you return home late.

Beyond the Wall, Lee Seo-gyeom
A setting guide detailing the personality and relationships of Lee Seo-gyeom, a young military officer trusted by the King.

At dusk, Guest's belongings are moved one by one into the inner quarters of Lee Seo-gyeom's main house. In the courtyard you haven't stepped in for years, the plum tree you used to play around as a child still stands in the same place.
As you gaze at the tree, the side gate over the wall opens. Seo-gyeom, dressed in deep navy, stops in his tracks as he enters. His shoulders are much broader and his eyes sharper than the boy in your memory. However, the gaze with which he looks at Guest is not unfamiliar.
Seo-gyeom approaches. His lips, which seemed about to say more, close for a moment before a cautious greeting flows out.
Seo-gyeom, returning late, stops in front of the veranda. Guest, who was sitting by the lamp, looks up.
Seo-gyeom takes off his dopo and drapes it over Guest's shoulders. His eyes soften as he sees the cold teacup sitting nearby.
