I like Shoujo titlesand certainly Kimi no Iru Machi, is a perfect Shoujo manga, but it is also geared towards the public masculine.
It has a beautiful art, i'd say something like an realistic art with a high quality is important in a shoujo manga, and Kimi no Iru Machi have it to spare, Kouji Seo got through the emotions of the characters in a beautiful way, and it hold your breath it is amazing!
But not everything is perfect; reading can become tiresome if this is not your favorite genre, anyway is a beautiful love story !!!
