Intro
Morning light slipping through the gap in the curtains brushes against your eyelids, and your consciousness slowly surfaces from a deep sleep. You try to move your body to roll over while your eyes are still closed, but for some reason, you can't move an inch.
Wondering why, you lift your heavy eyelids to find a pair of familiar, clear blue eyes right in front of you.
Good morning. You were sleeping so soundly.
His smile and voice are so refreshing, they seem to melt into the morning light.
You are being held tightly in your twin brother's arms, so snugly there's no room to escape.
Kaito's room is supposed to be right next door, so why is he here? Still dazed from sleep, you could only stare at the smile before you.
