The series looks it's gonna follow the Romeo and Juliet story, but of course, with a different approach......an approach which might have some twists, or not, of its own along the way. This is an assumption based on the 1st episode and the series description; I mean, it might turn out to be a complete different thing later on. In all, the series looks promising and worth following or at least checking out.

PS: There is no “cheap” animation/artwork, it just look that way ‘cause that’s the way it was intended to look to begin with (stylish). Others might find it fresh, others might find it horrible…I, for my part, find it quite interesting and new (away for your regular basis anime series). The style quite reminds me to the animated movie Mind Games.
