Koizumi Risa an unusually tall high school girl, meets the "vertically challenged" young man Otani Atsushi. They find common ground in height anxieties and interests. Risa (Ema Fujisawa), a tall Japanese girl, gets rejected by a boy because she is taller than him. Otani (Teppei Koike), a short Japanese guy, gets rejected by a girl because he is shorter than her. Obviously these two would make the oddest of couples and would never be a good match for each other right? Well love doesn't always follow such logic as Love Complex shows.
