Whilst it's fair to say Yankee-kun to Hakujou Girl is a really wonderful romcom it's actually a fair bit more. For a light series, it really touches on some of the challenges and prejudices that exist within society particularly with regard those with disabilities. It's handled really well though without being preachy or getting too deep and you can't help but smile at the way the main cast react to the circumstances.
It's never heavy going either. As with good romcoms, the drama is relatively light, the sweet moments really endearing and the comedy well balanced. Both the story and romance itself progresses at a satisfying rate and you're never left ranting at any of the characters for being 'dense' or making stupid decisions. It's really very natural and the extended cast get some nice development as well.
Overall, a really great read for a light-hearted romcom with a bit more thought-provoking depth to separate it from the rest.
