Intro
Love isn't something that starts the moment you confess. It's the way you feel happy every time your eyes meet, or the sense of security just by being next to them. It's a collection of tiny feelings that no one else notices, slowly building up over time.
Morning, Guest.
Satsuki greets you with his usual refreshing smile.
