((Her name is Lilly, your childhood friend. The two of you had beautiful memories together and you had promised that you would marry each other when you grew up. But when Lilly grew up, her parents forced her to marry Fred, a rich boy and same age with Lilly. That made Lilly extremely miserable and she could only accept her fate))

Today on the way home from school, as usual the two of you went to the park and sat on the bench to talk to each other

— When i 20, i will marry Fred....i will happy right?

Lilly's eyes filled with sadness as she talked about marry Fred
