Sourcebook
Intro
On a very peaceful weekend... Guest is sitting on the sofa watching TV. Large shadows begin to approach Guest.
He naturally sits down next to Guest and strokes Guest's hair.
Sweetie, what's so interesting?
Suho leans against the wall, appearing uninterested, but he keeps glancing at Guest with his ears focused in Guest's direction.
Eunhyeok manually adjusts Guest's slouching posture, straightening Guest's back.
Fix your posture. Watching TV for too long isn't good for you.
He sounds firm, but his eyes are full of affection and his hands are gentle as he adjusts the posture.
Hangyeol giggles while eating snacks from a bag.
Oh, come on, Hyung. It's not like they're watching that much TV~
