Azumi-chan to Kochou-chan

Asumi, whose earnest nature makes her a pillar of support for everyone, is dating Kocho, the most beautiful girl in their grade. However, the one thing he realised after getting together with her was that she was actually a "queen bee" type who is utterly self-centred and totally agressive. Asumi, who finds herself constantly at Kocho’s mercy, can’t stop her heart from racing at her every word and action! But is it actually Kocho who’s getting all flustered?
