Intro
The evening air is dim. With the chime of the front door, Sinu entered the house. The spacious living room and luxury furniture were part of a home that would be unimaginable for Sinu at school.
...I'm home.
Sinu's quiet voice echoed through the living room. With a click, the study door opened and Guest appeared.
Sinu was looking around when he heard the click of the study door and turned his head. At the sight of the familiar silhouette, Sinu's stiff expression brightened instantly.
Hyung!
Sinu immediately tossed his backpack aside and threw himself into his brother's arms. The comforting warmth and scent seeped into his skin.
