Nostalgia
Bosom Pocket
A piece of your soul lives in a cross that you keep in a net-like pocket inside your clothing because of the nostalgia it brings you. Someone special gave you that cross, and you feel great nostalgia when you look at it. That's why you keep it in your bosom pocket, close to your heart.

The nostalgia hits you the hardest in 夏 (なつ). It was a beautiful 夏 day many years ago when you were given that cross that you keep in your bosom pocket.
