Abe-kun's Got Me Now!, Volume 1 (Abe-kun's Got Me Now! #1-4)

Akari couldn't think less of her school's karate champ, Abe-kun, despite him being the national champion. He's giant, uncouth, and couldn't be more different than her sweet angel and childhood friend, Takuto. But when Abe-kun injures his arm protecting her, she takes it upon herself to get him healed - after all, the school's pride is at stake - but finds the tables suddenly turned when he confesses to her! Now she's the goal he's aiming for, and she'll soon find out how driven a national champion can be!
