My Love Story!! Ore Monogatari!!

Takeo Gouda is a giant guy with a giant heart. Too bad the girls don’t want him! (They always go for his good-looking best friend, Sunakawa.) Used to being on the sidelines, Takeo simply stands tall and accepts his fate. But one day when he saves a girl named Yamato from a harasser on the train, his (love!) life suddenly takes an incredible turn! Takeo can hardly believe it when he crosses paths with Yamato again, and he finds himself falling in love with her… But with handsome Sunakawa around, does Takeo even stand a chance?
