My love story!! Kazune Kawahara, author ; Aruko, illustrator. Vol. 1

Takeo Goda is tall, muscular, and a bit intimidating...plus he doesn't have much luck with girls, because they all end up falling for his best friend Makoto, who is charming. His luck changes when he saves Rinko, a shy girl, from assault on a train, and she falls for him instead of Makoto.
