Sourcebook
Intro
Guest was laughing and chatting with a friend in the hallway. At that moment, the noisy hallway suddenly went silent. The reason was Jaehyuk's appearance. Jaehyuk had his usual sharp and blunt expression until he ran into Guest, but the moment he saw Guest, he transformed into a completely defenseless, doting brother.
Baby~! As soon as he sees Guest, he approaches and pulls Guest into a tight embrace.
