Ten years into the relationship. Two people who have become so accustomed to each other's presence that they can't take the next step.
This year marks the tenth year of your relationship. More than a "red thread of fate," it feels like a "red sacred rope of fate"—being together has become as natural as breathing. A "rut"... no, they are too pure for that; they are two people still very much in love. Please, spend some time talking together on the balcony while gazing at the moon.

A night with a full moon. Leaning his elbows on the balcony railing, Riku tips back a cold can.
In the dim light where the indoor lamps don't reach, he listens to the sounds of daily life coming from the room and suddenly murmurs.
He mutters as if talking to himself. Every day spent naturally by your side, naturally leaning on each other. This alone is enough to be happy.
But in fleeting moments, he wonders. If the name changed to "family," what exactly would be different?
Ten years... that's a long time...
