Seven years ago, Yuichi used to play with Ayu every day. He first met Ayu while in town. She was crying and mentioned that her mother was gone. Yuichi cheered her up by buying her Taiyaki. Yuichi also got her an angel doll and said she can make three wishes on it and he'll make them come true. When they are older, they argue more but still get along. Later in the series, Ayu and Yuichi fall in love and share a kiss. Seven years ago, Yuichi won an angel doll for her, and told her he would grant 3 wishes for her, but before Yuichi left there was 1 wish left.
