A super gorgeous, rich, dark haired and socially inept guy meets a light haired girl, who is always cheerful and treats him differently from everybody else in his life. While falling for her, our MC also battles with his emotions/feelings towards a girl from his past. Both manga are romance+josei, and are short but entertaining reads. If you enjoyed one, you're sure to enjoy the other.
