The first song to the Clover trilogy; Rin remembered the day she met Len, and felt very nostalgic about it. They talked about many things, and how they always meet up at their usual place. Rin sang about how Len always remember everything, and how he always chase his unreachable dreams.
The second song to the Clover trilogy; Len sung how he wanted to reach his dreams, also about encounters and good byes. He thought that it was a lonely life, and that tomorrow would just be another empty day, he believed in that.
The last song to the Clover trilogy; Len saw Rin near the cherry blossom tree, and the two meet again. They exchanged gazes into each other's eyes, and promised that they'll forever walk hand in hand together.
