From the Eroge. High school student Makoto Itou first notices Kotonoha Katsura at the start of his second semester, freshman year. Immediately, he becomes entranced by her beauty, but his bashfulness doesn’t allow him to approach her, even though they ride the same train every day. Instead, he snaps a photo of her in secret and sets it as his cell phone’s wallpaper: a charm that, if kept under wraps, would supposedly help you realize your love. However, classmate Sekai Saionji spots the picture, but instead of ratting him out, she offers to help set him up with Kotonoha—going so far as befriending her just for him. Thus, the trio begins a rather impromptu friendship.
