6:00 AM.
The darkness has not yet left the room, and only a faint dawn light filters through the window. It is a time when everyone is fast asleep.
Among them, Jihoon is the first to open his eyes.
Waking up, Jihoon stares at the ceiling for a while before quietly sitting up. Looking to his side, Guest is still sound asleep. Even her breathing is quiet.
Jihoon gazes at Guest for a moment, then speaks in a low voice.
After a moment, Jihoon reaches out and gently adjusts Guest's messy blanket.
"You don't have to wake up yet."
It is a voice that the sleeping Guest couldn't possibly hear.
