Lovely Complex - Risa Koizumi The protagonist of Lovely Complex, Risa Koizumi is not your average Japanese high school student. Standing 172 cm tall (about 5' 7'), Risa's height is well above that of most Japanese girls her age; ironically, her name means 'little spring'. She compares herself and is compared by others to a giraffe. Risa can be impulsive and strong-willed at times, and is rarely willing to display her softer side. The team of herself and Otani is known throughout the school as 'All Hanshin-Kyojin'. She had a crush on Suzuki before he started dating Chiharu. Risa starts developing feelings for Otani and soon admits to herself that she likes him. She then starts trying to confess. Failing the first time, Nobuko and Nakao try to help, Nobuko often giving Risa advice on what to do. Finally she very directly tells him. She immediately says she regrets it, and tells Otani to pretend it never happenened, but her true feelings come out, and tells Otani once again, that she likes him. Otani responded that he couldn't see her as a girlfriend yet, so her new goal is to make Otani regret that and make him like her as well. However, eventually, Otani realizes his feelings for her and they become girlfriend and boyfriend. Atsushi Otani is one of the main characters of Lovely Complex. He is very short for a boy, standing 156 cm tall (about 5' 1'). Like Koizumi, Otani's name (roughly, 'big valley') is a pun on his diminutive stature, and he can be thoughtless and rude; at heart, however, he is kind and a little silly. Otani is also the star player of the school basketball team. His ex-girlfriend is Mayu Kanzaki, the manager of his middle-school basketball team. She broke up with him for a much taller boyfriend, and this is one of the reasons Otani is sensitive about his height, but he later finds out that wasn't the reason she broke up with him, it was because she was in love with someone else already who just happened to be tall. He doesn't know quite yet how he feels about Risa, and only responds that he can't see her as a girlfriend (at the moment) when Risa confessed. But later, he realizes that he does care for her, and he kisses her. Later on in the series, Otani gets the wrong idea when Risa keep doing suspicious things with her co-worker Kohori, and then breaks up with her. However, after seeing how devoted Koizumi is to him, Otani reconsiders and they make up on Christmas Eve.
