One summer afternoon, a girl talked to me on my way home from school. "Hey, let's go home together..." The girl's name is "Anri". We are childhood friends, but she is one of the best honors students in the school! On top of that, she's a super beautiful girl and the ace of the swimming club! I haven't spoken to my childhood friend, who has become a flower of Takamine, the exact opposite of me, for a while... Such a girlfriend invited me to her home. Before I knew it, she had grown up. A sweet summer spent with a girl begins now! !
