It was a sunny day and the green grass at a park in Kyoto was beautiful with some fallen leaves. Among them I picked up one leaf and examined it closely. Just like four leaves clover which bring good luck but is not easy to be spotted on the ground, I consider myself lucky to have found a heart shape from that maple leave on that day. Whether it is a broken or mended heart, it depends on your feeling and imagination. Anyway, there are actually five hearts. Can you see that?
